Terahertz Visible Broadband Beamsplitters
Terahertz Visible Broadband Beamsplitters
Our Terahertz Visible Beamsplitter is 2 in. diameter with an ITO coating optimized for reflecting terahertz wavelengths and transmitting visible wavelengths. Ideal for beam combining or separation, the substrate is made of high quality N-BK7 glass with the front surface optimized for terahertz wavelengths and the back side coated with a broadband antireflection coating optimized for visible wavelengths.
- ITO front surface optimized for 1-120 Thz
- AR coated back surface for visible wavelengths
- High quality N-BK7 substrates
- Beamsplitting ratio maintained over wide wavelength range See All Features

Features
Reflecting Terahertz Wavelengths
ITO or Indium Tin Oxide is used to coat the front surface. This ITO material is very effective in reflecting terahertz wavelengths.
Transmitting Visible Wavelengths
The beamsplitter is made of high-quality N-BK7 glass with good index homogeneity and low bubble inclusion. The backside is coated with a broadband antireflection coating optimized for transmitting visible wavelengths.
