This listing is for the sale of one (1) replacement window with the following characteristics: Material: N-BK7 Glass. Dimensions: 1" (25.4 mm) OD, 0.197" (5 mm) Thickness. 0.5° Wedge Between Transmitting Surfaces. Surface Flatness: λ/20 Over Central 10 mm, λ/10 Over Entire Clear Aperture. These windows are suitable for visible and NIR laser applications. The 0.5° wedge helps prevent unwanted etalon effects, fringe patterns, and cavity feedback. The high surface flatness prevents beam distortion. These windows are uncoated for use over their entire optical range. These windows are compatible with Ideal Vacuum's glass gas cells, Habanero reference cell furnace (up to 619 °C), and Serrano reference cell heater.
