Shortpass Filters

KUPO Optics' Shortpass Dichroic Filters epitomize precision optical engineering. Fabricated with meticulous hard dielectric thin-film coatings, these filters reflect our dedication to quality and accuracy. By precisely transmitting shorter wavelengths while blocking longer ones, they provide sharp, vivid colors and precise spectral control, vital for applications demanding meticulous light management.

Our advanced Ion Assisted Deposition (IAD) technology and cutting-edge planetary-running coating machine ensure uniform, resilient thin-film layers on the glass substrates. This translates to remarkable consistency in optical specifications across different filters, guaranteeing optimal performance in every application. The high-density coating not only enriches color vibrancy but also substantially strengthens the filters against UV, heat, and environmental degradation, outlasting traditional gel filters in durability.

KUPO's Shortpass Dichroic Filters play an essential role in a wide spectrum of fields. In laser technology, they enable harmonic separation and beam shaping, crucial for achieving precise laser output. In machine vision systems, they facilitate color sorting and object recognition by isolating specific color bands. In medical diagnostics, they enhance fluorescence microscopy and flow cytometry by selectively transmitting desired fluorescence signals.

With over 25 standard colors and custom color development options, these filters offer the adaptability to fulfill the specific needs of your project. Each filter conforms to the rigorous MIL-M-13508C standards, reaffirming KUPO Optics' promise to deliver reliable, long-lasting components for your optical solutions.
