230-900nm Wideband UV Laser Beamsplitter Plate 45R:55T Applications
Spectrophotometers
Spectrophotometers typically employ deuterium and tungsten-halogen light sources to cover the full 230–900 nm wavelength range. Standard beamsplitters can cause energy attenuation in the ultraviolet region. A broadband beamsplitter covering 230–900 nm ensures uniform beam splitting across this wide range, thereby enhancing the instrument’s accuracy.
Multi-wavelength Fluorescence Microscopes
In multiplexed fluorescence imaging—where excitation and emission wavelengths span the ultraviolet, visible, and near-infrared regions—frequently changing beamsplitters can lead to optical path misalignment. A 230–900 nm broadband beamsplitter directs multi-wavelength excitation light onto the biological sample while simultaneously transmitting the weak fluorescence signals.
Broadband Tunable Laser Systems
Femtosecond lasers, optical parametric oscillators (OPOs), and supercontinuum sources output laser light with extremely broad spectra spanning hundreds of nanometers. When sampling or distributing the energy of these high-energy beams, the dispersion effects of standard optical components can distort the spectral profiles of the transmitted and reflected light. A 230–900 nm broadband beamsplitter allows broadband laser light to be transmitted and reflected into spectrometers or beam profilers.
