Optical filters are designed to control and refine specific portions of the light spectrum by transmitting, attenuating, or blocking selected wavelengths as required by the application. Their performance is achieved through the use of specialized optical glass materials and precision optical coatings.

At Poloptech, we provide a comprehensive range of optical filters covering ultraviolet (UV), visible, and infrared (IR) wavelengths. Our solutions include both absorptive and interference-based filters, developed to meet demanding performance criteria in high-precision optical systems. Depending on the application, filter characteristics can be achieved either through the intrinsic properties of the optical material or through advanced multilayer coating technologies.

Our optical filters serve a wide variety of sectors, including defence, medical, industrial, and scientific applications. They are used in systems requiring accurate spectral control, such as imaging, sensing, instrumentation, calibration, laser applications, and R&D environments.

Poloptech’s filter portfolio includes colour glass filters, UV and IR cut-off filters, blocking filters, heat control filters, calibration filters, dichroic filters, and neutral density (ND) filters with defined optical density values.

In addition to our standard product range, Poloptech also offers custom optical filter solutions manufactured according to specific design, dimension, coating, and performance requirements.
