Custom Lenses

We are engaged in the design and manufacture of lenses according to the customer's specifications and perform the following operations:

  • optical and mechanical design,
  • assembly of optical systems,
  • production of prototypes and small batches,
  • quality control and tests.

The optical components are made of crystals and glass, including Ohara, Schott and CDGM, and are coated for the following spectral ranges:

  • IR 8-14 μm (LWIR)
  • IR 3-5 μm (MWIR)
  • IR 0.7 - 1.4 μm (SWIR, NIR)
  • Visible 0.4 - 0.7 μm (VIS)

The lenses listed on this page have been designed and manufactured in our company according to individual requirements. The results of the work are examples of lenses of different complexity that you can order.
