It is an optical filter that selectively transmits light below a specific wavelength and blocks light of longer wavelengths.
The short pass filter can selectively transmit light below a certain wavelength while blocking light of longer wavelengths. This allows for effective handling of light in specific wavelength bands. (Do you have any of the following concerns?) ■ Is it customizable due to its high wavelength dependence? ■ Does performance decrease when light is incident at an angle, and can it be controlled? ■ Is there a possibility of reduced 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, so when it transmits wavelengths below a certain point, longer wavelengths are consistently blocked. 2) Design and customization available for the desired wavelength range We can design and coat according to the customer's requested wavelength range. 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 type of substrate and wavelength range when inquiring. 3) Component support available We can handle everything from substrate procurement to coating. It is also possible to cut into any shape and ship as components. However, we will need detailed drawings. 4) Measuring instruments We will always attach a measurement chart upon shipment, so please rest assured. 5) Cleanroom compliance The working environment maintains the necessary cleanliness for each stage 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 can selectively transmit 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 specific wavelengths of light to pass through while blocking other wavelengths. This helps to enhance the specific wavelength of laser light 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 at specific wavelengths.
