This is a one-sided grinding process that achieves a level of flatness and surface roughness that is difficult to attain with conventional one-sided grinding. While our main focus is on small lot products such as measures, we are also capable of mass production! We can also process on a per-sheet basis. *For more details, please refer to the PDF or feel free to contact us.

The 940nm bandpass filter is a bandpass filter that selectively transmits near-infrared light at 940nm. It has spectral characteristics that minimize the transmission (and maximize the reflection) of visible light and some infrared light. The film is formed using ion-assisted deposition (IAD), resulting in a shift-free and dense film. For more details, please contact us or refer to the catalog.

The 850nm bandpass filter is a bandpass filter that selectively transmits near-infrared light at 850nm. It has spectral characteristics that minimize the transmission (and maximize reflection) of visible light and some infrared light. The film is formed by ion-assisted deposition (IAD), resulting in a dense and shift-free layer. For more details, please contact us or refer to the catalog.

The visible light cut filter is a long-wavelength transmission filter that reflects visible light while allowing near-infrared light to pass through. It is suitable for situations where you want to use near-infrared light but do not want to be affected by visible light. This filter is also coated using ion-assisted deposition (IAD), resulting in a strong and tightly adhered film. For more details, please contact us or refer to the catalog.

The IR Cut Filter 3 is a dielectric multilayer film that does not transmit infrared light (reflects it) while allowing visible light to pass through. It is formed by ion-assisted deposition (IAD), creating a shiftless and dense film. Compared to IR Cut Filter 1, it is a wide transmission range IR cut filter that allows visible light to pass close to the near-infrared region. Additionally, it features an anti-reflective coating (AR) on the backside, enhancing the transmittance in the transmission range. It is capable of transmitting and reflecting not only visible light and infrared but also any wavelength as needed. This filter corresponds to the light absorption spectra of chlorophyll a and chlorophyll b, making it suitable for plant growth experiments. We provide consistent design and manufacturing of IR cut filters. We will design and manufacture according to customer requests, including specifications for half-wavelength, transmission band, and cut-off band. For more details, please contact us or refer to the catalog.

The IR Cut Filter 2 is a dielectric multilayer film that does not transmit (but reflects) infrared light while allowing visible light to pass through. It is formed by ion-assisted deposition (IAD), creating a shiftless and dense film. Compared to the IR Cut Filter 1, it is a wide transmission range IR cut filter that allows transmission up to part of the near-ultraviolet region. Additionally, it features an anti-reflective coating (AR) on the backside, enhancing the transmittance in the transmission range. It is also capable of transmitting and reflecting arbitrary wavelengths, not just visible light and infrared. We provide consistent design and manufacturing of IR cut filters. We will design and manufacture according to customer requests, including specifications for half-wavelength, transmission band, and cut band. For more details, please contact us or refer to the catalog.
