Midwave Infrared Lens

The series of Midwave Infrared lens (MWIR) mainly include:

1) Large-aperture infrared lens, suitable for use scenarios where the temperature difference range is small and high-sensitivity detection is required;

2) Athermal infrared lens, suitable for ambient temperature requirements of -40°C~+60°C, without focusing treatment;

3) Wide-angle infrared lens, suitable for panoramic observation requirements, with the advantages of super large field of view and large depth of field;

4) The zoom infrared lens, including a variety of dual-field zoom lenses and continuous zoom lenses, can meet different needs.


1) Simple interface

2) Easy assembly

3) Extensive adaptation

4) Free of secondary development

5) Directly face integrators
