Sigma optical polarization filter

Product Introduction

Due to the polarizing filter being sandwiched between the protective glass plates, it is not easily damaged and can be used to wipe away stains.
Due to being fixed on the frame, the components are easy to operate and can be conveniently installed inside the bracket.
There are three types available: visible light, ultraviolet, and infrared.
Both sides are coated with anti reflection film, which can reduce the return light or stray light from the light source.

▶ Undertake the manufacturing of products in sizes or without frames outside of the product catalog.
▶ If there are other requirements for transmittance or extinction ratio, wavelength spectrum region, please inquire at the business department.
▶ There are also Gran Thomson prisms (GTPC) with high extinction ratio or transmittance available.

▶ In addition to polarization characteristics, dichroic polarizing filters also suffer from light loss due to absorption.
▶ Due to the use of heat-resistant resin film, please do not use it near high-energy lasers or high-temperature light sources.
▶ Due to the variation of extinction ratio with wavelength, purple light can sometimes be observed after extinction.
▶ The vertical direction of the polarization direction relative to the transmitted light is marked on the frame.
