Microlens

is an innovative company specializing in manufacturing of high quality micro-optical components.

Our patent protected technology is a result of many years of research, which enables a new paradigm for mass manufacturing of microlenses.
We specialize in the production of Nanostructured Gradient Index Micro Lenses (nGRIN). Our unique technology allows to manufacture lenses as small as 10-50 µm of diameter. They are achromatic within the visible range, but also in the infrared (800nm – 1550nm). Besides single lenses we manufacture also matrixes of nGRIN lenses.

Our products are the enablers for the miniaturization of devices such as cameras, telecommunication waveguides, endoscopes, lasers, displays, computers.

Our products

Microlens proposes Nanostructured Gradient Index Micro Lenses (nGRIN) with a diameter of 20-50 µm which are an order of magnitude smaller than existing GRIN lenses.

The product is the enabler for the minaturisation of existing optoelectronic devices.

The lenses are achromatic within the visible range, but also in the infrared (800nm – 1550nm), which is a unique feature for a single lens system.

Single Microlenses

Microlenses Matrix

nGRIN lens features:

Possibility of obtaining „on demand” refractive index distribution which allows to improve the optical quality.
As many lenses are created in one manufacturing process the variability of parameters within a product batch is very low.
Flat Surface – easy integration with other systems eg. fiber optics.
Possibility to create a microlenses matrix with hexagonal shape lenses.
Design of „on demand” shapes of microlenses.
Focusing beam inside the lens (No change in optical properties after immersion in a liquid).
Ability to obtain elliptical lenses and pre-set astigmatism to correct optical defects of the light source.

Main applications

Telecom

SEMICONDUCTOR LASERS

Our offer

Custom made products:

Our products are offered in short series production and can be customized in order to fully meet your specifications.

Those products can also be integrated into custom optical systems thanks to our optical design and optomechanical departments.

Development:

One of our biggest advantages at Microlens is our prototyping capability.
