The lenses stick on glass by electrostatic force, without glue. For this reason, when they lose stickiness, they usually need to be cleaned from grease of dust on the rear side.
There are 2 lateral adhesive bands behind the film to help the adhesion on every surface. These adhesive bands have been engineered for multiple use (>100 of times) in proper conditions. These bands reduce their stickiness when they get dirty. In order to extend the optimal usability of the Blips lenses to very long time, we provide a spare adhesive tape within every Blips kit which allows up to 10 bands replacements.
BLIPS is designed to stick onto both polished and textured surface. We achieved excellent results with aluminum unibodies (e.g. Iphone 6) as well as more textured phones (e.g. Samsung Galaxy S6 or Oneplus 2). BLIPS works even better on glass and works just fine on plastic
BLIPS is compatible with virtually every smart device on the market. Depending on the device architecture (e.g. upper front facing speakers), BLIPS can be placed horizontally or vertically and can be cut to adjust to many different sizes and shapes. BLIPS can also be used to blur images on your computer’s camera, TV, security camera in order to protect your privacy and can be used over and over again without leaving residues
– With BLIPS applied on the camera of your device, take a picture of a ruler without any digital zoom
– Measure on your screen the distance between two tick marks
– Divide this distance by the real distance between the two tick marks on the ruler
Other products claiming very high magnification levels, without specifying measurement systems, result of significantly lower magnification applying this straightforward method.
The level of optical power (i.e. magnification) has been selected with attention in order to provide the best whole of optical performance and usability. Moreover, magnification is not an important parameter for digital optics (and microscopy); the most important parameters are resolution, i.e. the ability to distinguish tiny features, and field of view, i.e. the imaged area without scanning your device on the sample. With proper lighting BLIPS Micro can achieve a resolution <4microns, and its field of view is of about 5mm × 3mm. For BLIPS Macro they are about the double.
- Higher magnification needs very short deep of focus, significantly smaller field of view and very short working distance.
- Shorter deep of focus makes very difficult to get images in focus using hand-held devices
- Smaller field of view makes very difficult to find the sample you want to observe behind the smartphone.
- Very short working distance do not allow to film or shoot nature subjects like insects, to look inside flowers, or to check inside small 3D structures.
Higher optical magnification can be achieved with different systems where sample and optics are rigidly kept at a defined distance, but the fields of applications are partially different with respect to the targets of BLIPS
When you apply BLIPS Macro you can see on your screen an image magnified about 8-15x without the use of additional digital zoom. The range 8-15x is due to the differences among the cameras of the smartphones or tablets employed.
With BLIPS Micro you can see on your screen images magnified about 16-28x, while the magnification power for the Blips Ultra lens is of 30-45x. With the Blips Ultra lenses it is possible to detect details of about 3 micron (3/1000 mm).
The method used to measure this magnification level is the following:
- Take the picture of a ruler, with BLIPS applied on your smartphone, without using digital zoom
- Measure on your touch screen the distance between two tick marks
- Divide the distance measured in this way by the real distance between the two tick marks on the ruler
Other products claiming very high magnification levels, but without specifying how it is measured, result of significantly lower magnification applying this straightforward method.
The number of pixels of your camera sensor is usually not an issue. Indeed, the higher the magnification, the lower the number of pixels required to achieve the same resolution.
A rough numerical evaluation for BLIPS Macro is following:
Field of view: 10mm – image 16:9 @ 5.99MPixel (3264×1836)
Every pixel side corresponds to 10mm/3264 ≈ 3microns
