Product Description
The METICULAB UV Filter series provides precision spectral filtering for i-line steppers, mercury lamp systems, and excimer laser applications. Available in narrow bandpass, long-pass, and short-pass configurations, these filters deliver high transmission with steep edge transitions and excellent out-of-band blocking across the 190nm–450nm range.
Whether you need to extract specific mercury spectral lines, block unwanted wavelengths in lithography systems, or protect optical components in high-power laser environments, METICULAB UV filters provide reliable, high-performance solutions tailored to your system requirements.
Core Feature: "Precise wavelength extraction with superior out-of-band rejection" — critical for photolithography and high-precision spectroscopy.
Available Filter Types
Narrow Bandpass
Mercury i-line & spectral line extraction with high rejection.
Long-Pass
Transmit above cutoff wavelength, block shorter wavelengths.
Short-Pass
Transmit below cutoff wavelength, block longer wavelengths.
