43-968 152.4 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=609.6mm Uncoated

The 43-968 is a high-precision concave spherical mirror, boasting a large 152.4 mm diameter and a thickness of 25.4 mm at the edge. This mirror is crafted from Borofloat33, a specialized glass renowned for its excellent optical properties, making it an ideal choice for various applications.

The mirror's geometry is spherical, with a radius of curvature (R1) of -1219.2 mm, indicating its concave nature. This curvature, combined with the mirror's substantial diameter, provides a generous effective focal length (EFL) of 609.6 mm. This long EFL is beneficial in applications requiring a tight beam focus or a large working distance.

The mirror is uncoated, meaning it does not have any additional layers to enhance its reflectivity. This can be advantageous in applications where broadband reflection is required, or where specific coatings may interfere with the desired spectral range. However, it's important to note that uncoated mirrors typically have lower reflectivity compared to their coated counterparts.
