DPSQ-30-10H Fused Silica Equilateral Prism; 30mm Uncoated

OptoSigma's DPSQ-30-10H is a high-quality fused silica equilateral prism, designed with a 30mm edge length and uncoated for versatile applications. This prism is a part of the DPB-DPSQ-DPTIH11 series, known for their precision and reliability in the field of optics.

The prism's equilateral design, with internal angles of approximately 60 degrees, allows for efficient and consistent light refraction. This is particularly useful for dispersion applications, where the prism's ability to separate light into its spectral components is crucial. The wavelength specified for this prism is 632.8nm, which is within the visible light spectrum.

The DPSQ-30-10H is crafted from fused silica, a material highly valued for its excellent optical properties. Fused silica, or UVFS, offers a low coefficient of thermal expansion, high homogeneity, and resistance to chemical etching. This makes the prism suitable for use in environments with varying temperatures and humidity levels.

The prism's geometry is defined by its 30mm edge length (a = 30mm, b = 30mm) and an alpha angle of approximately 60 degrees. This volume-based, equal prism shape ensures minimal beam deviation and maintains the integrity of the light path.

Notably, this prism is uncoated, meaning it does not have any additional layers of material applied to its surface. While coatings can enhance certain optical properties, an uncoated prism can be advantageous in applications where minimal reflection or dispersion is desired.
