It is an optical filter that selectively transmits light below a specific wavelength and blocks light of longer wavelengths.
A short-pass filter selectively transmits light below a specific wavelength (800nm) and blocks light of longer wavelengths. This allows for effective handling of light in a specific wavelength range. (Do you have any of the following concerns?) ■ Is it possible to customize due to high wavelength dependence? ■ Does performance decrease when light is incident at an angle, and can it be controlled? ■ There may be a decrease in transmittance when blocking specific wavelengths. ■ Can it cause chromatic aberration? ■ Is it difficult to control multiple wavelengths simultaneously?

basic information
1) Features: ■ Excellent wavelength selectivity ■ Sharp edge filter It has the characteristic of transmitting or blocking light with a steep change. ■ Symmetry Typically shows symmetry in both the transmission band and the blocking band, meaning that if it transmits wavelengths below a certain point, longer wavelengths are consistently blocked as well. 2) Custom design and coating available for desired wavelength range We can design and coat to match the wavelength range requested by the customer. Control in both the transmission region and the blocking region, 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 substrate type and wavelength range when inquiring. 3) Component support available We can handle everything from substrate procurement to coating. It is also possible to cut to any shape and ship as components. However, we will need detailed drawings. 4) Measurement instruments Rest assured that we will always attach a measurement chart upon shipment. 5) Cleanroom compliance The working environment maintains the necessary cleanliness from coating to inspection, and we have a thorough system in place to address minor film defects (such as foreign substances in the film).

Applications/Examples of results
◆Fluorescence Microscope Used to separate different fluorescence colors in a fluorescence microscope. For example, when observing multiple fluorescence colors simultaneously, it allows selective transmission of the emission wavelengths of each fluorophore. ◆Spectrometer and Spectrophotometer Used to block specific wavelengths of light and detect the remaining light. This allows for the analysis of light in specific wavelength bands. ◆Laser Applications In laser systems, short pass filters are used to allow light of specific wavelengths to pass through while blocking other wavelengths. This helps to enhance the laser light of specific wavelengths and remove unwanted wavelengths. ◆Image Sensing In cameras and image sensors, short pass filters are used when it is necessary to transmit light in a specific wavelength range while cutting off other wavelengths. This can enhance information of specific wavelengths.
