This product is an optical filter used for fluorescence observation. It transmits only the fluorescence emitted by the target fluorescent substance while blocking excitation light and other unwanted light, creating an environment conducive to fluorescence observation. Since the excitation wavelength and fluorescence wavelength differ depending on the fluorescent reagent used, filters suited for fluorescence observation are employed. 【Features】 ■ High blocking performance for excitation light and other unwanted wavelength bands ■ Measurement guarantee of OD6 ■ Achieves high-contrast fluorescence observation ■ Custom design available upon request *For more details, please refer to the related links or feel free to contact us.

This product is a color matching filter that reproduces the sensitivity curve of the human eye, allowing cameras and sensor devices to achieve the same visual perception as humans by inserting it between them. By layering dielectric films on glass and utilizing interference effects at the multilayer film interfaces, it achieves the desired transmission spectrum. Customization of spectral transmittance and the deposition of anti-reflective coatings and UV-IR cut filters on the backside are also possible. 【Features】 ■ Achieves f1' below 2% ■ Passes various reliability tests with a dense film ■ Customizable upon request *For more details, please refer to the related links or feel free to contact us.

This product is a filter that transmits only specific wavelengths and cuts off other light. It is widely used in analyzers, measuring instruments, optical communication devices, sensors, and ultraviolet irradiators. It provides sharp wavelength separation and high transmission rates. Fluorescent filters used for fluorescence observation require high optical density, and we can ensure this from design to manufacturing and spectral measurement. 【Use Cases】 ■ Medical and Healthcare ■ Analysis and Sensing ■ Semiconductors ■ Communication *For more details, please refer to the related links or feel free to contact us.

This product is an optical filter that utilizes light interference from thin films to reflect specific wavelengths of light while allowing other wavelengths to pass through. By allowing the desired wavelength of light to pass through and reflecting the unwanted wavelengths, it is possible to separate wavelengths. We offer a "UV Cut Filter" that cuts ultraviolet (UV) light while allowing visible light to pass through, an "IR Cut Filter" that cuts infrared (IR) light while allowing visible light to pass through, and a "Non-Polarizing Edge Filter" that suppresses the separation of transmittance. 【Product Lineup】 ■ UV Cut Filter ■ IR Cut Filter ■ Non-Polarizing Edge Filter *For more details, please refer to the related links or feel free to contact us.

This product is an optical filter that closely approaches the standard relative spectral sensitivity defined by the International Commission on Illumination (CIE) in its spectral transmittance curve. By stacking dielectric films on glass and utilizing interference effects at the multilayer film interfaces, the desired transmission spectrum is achieved. It is used for measuring brightness and luminance. 【Features】 ■ Achieves less than f1'2% ■ Passes various reliability tests with a dense film ■ Customizable upon request *For more details, please refer to the related links or feel free to contact us.

This product is a plate-type beam splitter used to separate incoming light into two components by reflecting part of the light and transmitting the rest. It can be used not only for "neutral separation," represented by half mirrors, and "two-color separation," which reflects a specific wavelength range while transmitting the rest, but also for manufacturing polarization beam splitters that separate p-polarized and s-polarized light from the incident light. There are prism types and plate types available. 【Features】 ■ Suitable for use in the ultraviolet range, or when laser resistance and heat resistance are required. ■ Design and manufacturing of non-polarizing beam splitters are also possible. *For more details, please refer to the related links or feel free to contact us.
