It is an optical filter that selectively transmits light below a specific wavelength and blocks light with longer wavelengths.
The short pass filter selectively transmits light below a specific wavelength while blocking 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 customizable due to its high wavelength dependence? ■ If light is incident at an angle, will performance decrease, and can it be controlled? ■ When blocking a specific wavelength, there may be a decrease in transmittance. ■ 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, so when it transmits wavelengths below a certain point, longer wavelengths are consistently blocked. 2) Design and customization available for desired wavelength range We can design and coat to match the desired wavelength range of our customers. Control in the blocking region as well as the angle of incidence are also 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 We will always attach a measurement chart upon shipment, so please rest assured. 5) Cleanroom compliance The working environment is maintained in a cleanroom with the necessary cleanliness for everything from coating to inspection, ensuring a thorough system against minor film defects (such as foreign matter 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 for the 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 other wavelengths. This allows for the enhancement of information at specific wavelengths.
