It is a filter designed to transmit light in two specific wavelength bands while blocking (preventing) other wavelength bands. It is ideal for surveillance cameras and similar applications.
1) Are you facing issues like this? ■ I want to pass visible light and part of the infrared wavelength (850nm), is that possible? ■ I definitely want to cut out the blocking range that causes noise. ■ Since there is a range of incident angles, can that be taken into account? ■ The shape is special, but can it be shipped as a part? 2) Dual-band pass filter (multi-band pass filter) This is a filter designed to transmit light in two specific wavelength bands while blocking (stopping) other wavelength bands. In addition to regular IR cut, it has the function to selectively transmit only specific near-infrared wavelengths (such as 850nm, 905nm, 940nm, 1064nm). For example, it is ideal for applications that require monitoring during both day and night by transmitting specific visible light and specific near-infrared light. With 40 years of experience, we have achieved sharp wavelength separation and high transmission rates. Our unique control technology during film formation allows for high durability and reduced shift.

basic information
1) Excellent transmission characteristics 2) Optimal design for substrates By utilizing the characteristics of the substrate used, we achieve the optimal filter through design. 3) Design and customization possible for desired wavelength range We can design and deposit (coat) according to the wavelength range requested by the customer. Control in both the transmission range and the stop band, as well as the angle of incidence, are important factors. We will design according to the characteristics of the substrate and the customer's requirements, so please provide the type of substrate and wavelength range when inquiring. 4) Component support also available We can handle everything from substrate procurement to film deposition. It is also possible to cut into any shape and ship as components. However, we will need detailed drawings. 5) Measurement instrument: FT-IR owned We will always attach a measurement chart upon shipment, so please rest assured. 6) Cleanroom compliance The working environment is maintained in a cleanroom with the necessary cleanliness for each process from film deposition to inspection, ensuring a thorough system against minute film defects (such as foreign substances in the film). 7) Safety and peace of mind No harmful substances to the human body are used.
