Low GDD Dichroic Shortpass Ultrafast Filters

TECHSPEC® Low GDD Dichroic Shortpass Ultrafast Filters

TECHSPEC® Low GDD Dichroic Shortpass Ultrafast Filters

×
  • Reduced Thickness for Limited GDD
  • Broad Transmission and Reflection Ranges 
  • Ideal for Ultrafast Laser Applications
  • Controlled GDD Specification Using In-House Metrology

TECHSPEC® Low GDD Dichroic Shortpass Ultrafast Filters feature thin substrates and a low group delay dispersion (GDD) coating, making them ideal for use with ultrafast laser sources. Designed for a 45° angle of incidence and covering a range of wavelengths, these spectral filters can be used with Ti:sapphire, Nd:doped, and Yb:doped fiber or glass lasers, as well as with optical parametric oscillators and amplifiers. TECHSPEC Low GDD Dichroic Shortpass Ultrafast Filters are ideal for ultrafast laser applications including multi-photon microscopy, nonlinear fluorescence, and femtosecond stimulated Raman spectroscopy. Please contact us if your application requires an ultrafast optical filter with a custom size or wavelength range.

Note: These filters are optimized for high spectral performance rather than high Laser Induced Damage Thresholds (LIDT). A typical LIDT for these filters is 1 J/cm2 @ 532nm, 10ns. Please contact us if you require a filter with a higher LIDT value.
