Infrared filter thermometer is composed of photodetector, optical system, signal processing, signal amplifier, display output, feedback source and radiation of the measured object.

This material was developed by OHARA based on our knowledge of High Homogeneity melting and Precise Crystallization. This material is produced under tightly controlled conditions and offers outstanding thermal, mechanical and chemical properties.

H-K9L crystal is also called H-K9L glass, which can also refer to glass products made of H-K9L material, which are used in optical coating and other fields. The light transmittance, refraction effect, hardness and texture are much higher than those of resin materials.

We has our own R&D team which can efficiently produce customized products. Now, we have stable production ability to produce regular or irregular customized products. Meanwhile, we also have superior management system so that we can supply products with high quality and best price.

Schott Sapphire, as one of the hardest, most durable and scratch resistant materials, offers a broad transmission range from UV to mid infrared wavelengths (250 - 5000 nm). The material is able to withstand extreme environmental conditions and temperature changes. SCHOTT offers sapphire materials, Raytek offers the machining process in different supply forms, dimensions, and in customized processing stages.

Hellma Materials Barium Fluoride is the material of choice for wide bandwidth applications covering the VIS, near-IR and mid-IR range. It is an optical crystal grown from highly purified synthetic raw material and features a superior internal transmittance (T > 99% @7μm) enabling advanced applications in thermal imaging, night vision and surveillance imaging using integrated VIS and IR detector channels. Low spectral dispersion makes BaF2 the preferred optical material for aberration and color correction.
