This is a bandpass filter that achieves a sharp rise and high transmittance in the infrared range (905nm). It is ideal for TOF sensors and LiDAR.
Are you facing any of these issues? - Is it possible to only transmit specific wavelengths in the infrared range? - I would like a bandpass filter suitable for TOF sensors. - I heard that the wavelength used in LiDAR is 905nm; can you create a film for that? - Since light other than the desired wavelength will cause noise, I would like to widen the stop band. - Given the range of incident angles, can this be taken into account? - Is it possible to mount this on AGVs or OHTs? The 905nm bandpass filter is a filter that transmits specific wavelengths by utilizing light interference through the deposition of dielectric films. Based on our proven results in visible light, we can achieve sharp wavelength separation and high transmission rates in the infrared range (905nm) by controlling the deposition process, making it ideal for photoelectric sensors (such as TOF sensors) that require delicate light. We have standard stock items available, so please consider them. https://www.e-coating.jp/stock/cat/filmtype/bandpassfilter/

basic information
1) Excellent infrared transmittance 2) Optimal design for substrates By utilizing the characteristics of the substrate used, we achieve the optimal filter through design. 3) Design and customization available 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 available We can handle everything from substrate procurement to deposition. It is also possible to cut into any desired shape and ship as components. However, we will need detailed drawings. 5) Measurement equipment: 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 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.
