The history of the Lens Technology is Primed Phone

Here is a brief history of the camera lens in mobile that has evolved.

  1. Sharp was the very first company that developed the camera phone.
  2. Sanyo SCP-5300 was the first camera phone to be manufactured in the U.S.
  3. The Audiovox PM8920, offered 1.3MP cameras.
  4. Firstly 2MP cameras were introduced by Nokia in their N90 model.
  5. Nokia also introduced 5MP cameras in their later N95 model.
  6. Samsung started building 8MP camera lenses for their mobile phones.
  7. Introduction of Smartphones completely stalled the mobile camera and then skyrocketed it with modern gen technology.

What are primed Phones?

Primed Phones can be termed as Flagship phones or premium level phones since these mobile phones are packed with heavy hardware specs which can easily handle tons of industry-leading apps and even heavy graphic oriented games.

Also provides an almost industry-standard camera which to some extent does beat outcrop sensor traditional cameras in terms of quality and effectiveness while capturing photos and videos.

All of these features are bundled together with tons more options and then given a premium look i.e. the physical body of the mobile phone which is usually in shiny metal texture although not weighing a lot.

Some examples of primed phones are iPhone Series, Samsung Galaxy S series, OnePlus Series and Google Pixel. Other companies are trying to replicate these brand models and launching their flagship versions of mobile phones.

The new Lens Technology

If we rewind to the era of the first iPhone in 2007 the camera present in the device was just 2 megapixels rear camera, and it didn’t feature any kind of front-facing selfie camera which is a common feature in the budget mobile phones these days.

The camera technology peasant in mobiles has evolved a lot with sensors featuring 108 megapixels, which are present on Samsung’s Galaxy S22 Ultra devices.

Along with impressive growth in sensor sizes, & megapixel counts present in smartphone cameras in the past decade. Along with massive improvements in the photography software versions.

On top of these changes, the lenses’ actual size that helps capture photos hasn’t seen any fundamental changes. Therefore it hasn’t made the mobile devices uncomfortable to hold or operate in their daily life.

The company “Metalenz” is referred to as a juggernaut since it is looking to disrupt the entire market of smartphone cameras with its single, flat lens mechanism utilising the “Optical Metasurfaces” technology.

Any camera built integrating this new tech will be capable of producing images of the best quality when compared to traditional lenses, since these lenses allow the sensor to collect much more light that makes the photos brighter. Along with allowing the camera form factor to retain its sleek form.

The “Flat Lens”

The major question revolves around how does it work?

It’s crucial to understand the working mechanism of camera lenses in today’s generation. The entire image processing system present in the smartphone might have multiple cameras present for example the latest iPhone 13 Pro has 3 rear cameras, and the Samsung S22 ultra has 5 rear cameras but every camera has these lens elements getting stacked on top of one another. In the iPhone 13, the camera sensor system utilises seven lens mechanism elements for processing images.

The implementation of a many-lens design for example the Galaxy S22 and iPhone can be termed to be superior when compared with a single-lens setup; since more light sequentially passes through every lens, therefore making the image gain added sharpness and clarity value.

In an interview with Oliver Schindelbeck, who is the innovation manager for Zeiss a company known for having specialisation in producing high-quality lenses stated “The optical lens present in a smartphone these days usually consists of lens elements ranging from four and seven, Since camera’s that uses only a single lens element will go through tons of aberrations such as distortion of the image.”

The use of more lenses allows manufacturers compensating for any kind of irregularities, for example, the chromatic aberration which refers to certain colours appearing on the edges of the image output and lens distortion which is referred to as straight lines that appear as curved lines in the image.

Although when there are multiple stacking of lens elements one on top of the other on the base does require more space on the vertical side of the camera module. These are some reasons for which the “bump” of cameras on smartphones has increased in size with the flow of time.

In an interview, Schindelbeck stated that a camera needs more space if it has multiple lens elements operating. While there are tons of other factors which contribute to the increased bump such as the use of larger image sensors and zoom lenses.

Top mobile manufacturing companies such as Apple have immensely increased lens elements gradually in their mobile devices, and while some, like Samsung, have started focusing on the “periscope” lenses technology which provides much greater zooming capabilities, while rest of the companies in the mobile manufacturing industry have remained stagnant with the stacked lens element mechanism system.

Schindelbeck further stated that optical lenses have become more sophisticated while adding more lens elements has led to the creation of stronger aspheric elements necessary for achieving a reduction in space size, yet this isn’t hailed as the groundbreaking revolution of the decade.

But the company Metalenz brings some fresh changes like using single-lens built with glass wafers ranging in size from 1×1 – 3×3 millimetres, therefore eliminating lens elements made with the use of plastic and glass for stacking over the mobile device’s image sensor.

This lens uses nanostructure technology which bends light rays in the correct way and therefore reduces tons of the shortcomings while capturing pictures or videos using traditional single-lens camera mechanisms.

In 2017, this core technology was formed after an entire decade of research conducted in collaboration with acclaimed physicist Federico Capasso, who is the co-founder of the company.

Since the light passes through multiple patterned nanostructures, under the microscopic level this lens looks like nano-tech circles with differentiable diameters ranging from one another.

The CEO Devlin also mentioned that “The mechanism is similar to the curved lens working when it speeds up or slows down to enable the light to bend, these lenses allow similar actions, therefore bending and shaping light by adjusting the diameters present in these circles,”.

All of this advanced technology system just enhances the image quality since it will help provide sharpness since it uses the multi-lens system, while the nanostructure mechanism reduces or completely eliminates any kind of image-degrading aberrations which are some common downsides in traditional cameras.

This new system delivers the flow of more light in the image sensors, therefore making the images appear brighter and sharper compared to traditional lens elements.

Along with all these benefits and changes in image quality the size of this lens won’t be affected therefore no change in the size will be made to the camera or phone design in general which is considered game-changing.

New Forms of Sensing

The Len company Metalenz has to enter mass production. Its first application will be to serve as the lens system of a 3D sensor in a smartphone.

The CEO Devlin has stated they are currently working on 3D sensors, which are similar to Apple’s TrueDepth camera which is used to implement the Face ID mechanism used for security.

Also, sensors illuminate the scene and use lasers for scanning faces, even though these sensors drain a ton of the phone’s battery.

But the company Metalenz mentioned developing light present in the image sensor, which will also conserve power. You might wanna ask why this can be good news for the mobile technology industry.

Well, if 3D sensors are present in the front camera of any phone and are used for face authentication systems, CEO Devlin mentioned their company will eliminate any need for having a bulky camera notch looming on top of the screen, for example, the iPhones notch design.

This genuinely helps reduce space usage of old lens mechanism elements and will enable numerous mobile phone developers to integrate these sensors and then cover these micro techs using the device’s glass display.

Devlin also mentioned the company Metalenz is also working on certain next-gen applications that have a reach beyond smartphones.

Since these kinds of tech will be implemented in instruments catering towards health care, AR and VR cameras, and even cameras present in automobiles. Let’s talk about spectroscopy.

It is used for detecting different wavelengths of light, and this kind of technology is generally seen in the medical health sectors since these techs are used for identifying certain specific molecules present in the blood samples.

The company also claims it will allow the user to collapse “any kind of tabletop optics into any single surface” the CEO also claimed all these complex features will be possible using a mobile phone just by adding their company’s specific integrated lens with the base camera lens.

FAQ:

  1. Does Phone Camera Lens Fall under the Well Constructed category?

Cameras in smartphones have become very necessary smartphones, therefore the lens construction quality has to be solid and perfect always.
