Infrared reflection prevention film: A filter that efficiently transmits the wavelength range of 9μm.

Bandpass filters are important in optical and infrared applications, providing many advantages such as improved signal accuracy, enhanced image quality, reduced environmental impact, energy savings, and increased safety. Therefore, materials and coatings that allow only specific wavelengths to pass through are used. Custom design and coating can be done to match the desired wavelength range. Are you facing any of these issues? - Is it possible to use resin on the substrate for weight reduction? - I want to allow only specific wavelengths in the near-infrared range; can this be adjusted? - I would like to cut visible light and long wavelengths; is this feasible? - I want to suppress light that causes noise and increase the sensitivity of the sensor. Can we discuss this? - Is it possible to process to chip size? Please see below for more information.

We have added a standard stock lineup for the "Near Infrared Bandpass Filter, Wavelength 940nm," which has received numerous inquiries! ■ I want to separate a few pieces for urgent product development and performance testing... ■ I just want to try it out for now... ■ I would like to make a slight change in shape for prototyping... At Adachi New Industry, we sincerely respond to such customer voices! In today's world where simulation technology has advanced, we will provide standard stock items to quickly meet customer requests, so please feel free to contact us! If you are considering a 940nm bandpass filter, please make use of our offerings. We provide filters that maintain their waveform even when the angle changes, meaning they are less likely to lose transmittance even if the angle is misaligned.

This is a filter that forms a multilayer film on infrared optical substrates made of Ge or Si, allowing efficient transmission of infrared wavelengths in the 9μm range due to the action of the interference film. Transmittance: Achieved a maximum of 93% (substrate: Ge). *This is not a guaranteed value. Reflectance: Achieved below 0.5% (at 9μm) (substrate: Ge). *This is not a guaranteed value. → The reflectance data graph has been updated! It can also be applied as a window material for detecting infrared radiation emitted from objects near room temperature. ◆◆ Are you facing any of these issues? - I want a filter with high transmittance as a window material for lasers. - The substrates that transmit infrared have low transmittance on their own, so I would like improvements. - Is it difficult to control the peak wavelength? - Since germanium is a material that is weak against scratches and water, can we achieve stronger characteristics? - Can measurements be taken in the far-infrared region?
