Lenses

LWIR lenses

LWIR - 8-12 μm - is the most common type of thermal imager. They work in the range of regular temperatures and are widely used in surveillance systems, medical and biometric thermal imaging. They are used for remote fire detection, satellite weather profile monitoring, air pollution monitoring and deforestation mapping.

This section lists some types of lenses we designed and manufactured.

We are also ready to design and manufacture lenses according to the customer's specifications.

Control of the main characteristics of the lenses (MTF, FCE, athermalization, etc.) is carried out on special optical benches of our own design.

MWIR lenses

MWIR range - 3-5 μm. Applications are numerous: monitoring the cooling process of glass manufacturing, measuring temperatures in incinerators, monitoring the soldering process in electronics manufacturing, etc. Providing near-diffraction characteristics, these lenses are suitable for infrared Fourier spectroscopy and thermal imaging microscopy applications.

VIS, NIR and SWIR lenses

VIS range - 0.4 - 0.7 μm

NIR range - 0.7 - 1.4 μm

SWIR range - 1.4 - 3 μm. The scope of application of SWIR lenses is diverse: perimeter security, border and seaport control, twilight and night vision, vision through smoke, fog, laser radiation detection, etc.

Dual-focus lenses and collimators

Opto-TL designs and manufactures dual-focus lenses and dual-focus systems "collimator + lens", the focal lengths in which are changed without changing the lenses.

Custom Lenses

LLC "Opto-TL" produces optical systems according to the customer's specifications and performs the following operations: design of the optical system, mechanical design of precision optical devices, assembly of optical systems, production of prototypes and small batches, quality control and tests.

Quality control of lenses

The measurement laboratory of Opto-TL is equipped with modern unique devices of our own design - optical benches OS-2000VD (visible range) and OS-2000IK (IR range). These devices control all the necessary parameters of lenses of various complexity. Our company has also created software with the help of which we have reliable results.
