32-826 76.2 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=152.4mm Uncoated

The 32-826 is a high-precision concave spherical mirror, boasting a 76.2 mm diameter and a 152.4 mm effective focal length (EFL). This mirror is crafted from Borofloat33, a low-expansion borosilicate glass, making it an excellent choice for applications requiring high dimensional stability and excellent transmission properties.

The mirror's geometry is defined by a radius of curvature (R1) of -304.8 mm, indicating a concave shape. The edge thickness is 12.7 mm, providing robustness and rigidity to the mirror. Despite its robust construction, the mirror remains lightweight, making it suitable for various optical systems.

The mirror is uncoated, offering bare glass reflection. This can be advantageous in applications where specific coatings may interfere with the desired spectral response or introduce unwanted reflections. However, it's important to note that uncoated mirrors typically have lower reflectivity compared to coated ones.
