The 20TZBS02-C Terahertz Visible Beamsplitter is 2 inches in diameter with an ITO coating optimized for reflecting terahertz wavelengths with resistivity &le,10 Ohms/Square and transmitting visible wavelengths in the 450 to 800 nm range. Ideal for beam combining or separation, the substrate is made of high quality N-BK7 glass with the front surface optimized for terahertz wavelength and the back side coated with a broadband antireflection coating optimized for visible wavelengths.
