SLSQ-25-60N 25.0 mm Dia. x -60.0 mm FL; Plano-Concave Lens Uncoated
The SLSQ-25-60N is a Plano-Concave Spherical Lens, 25.0 mm in diameter, uncoated, and sourced from OptoSigma. This lens is designed for use in a wide range of optical systems, offering a negative focal length of -60.0 mm.
The lens's geometry is characterized by a thickness of 5.0 mm at the edge and 2.0 mm at the center, providing a balanced structure for efficient light transmission. The lens's base shape is circular, ensuring uniform light distribution and minimal distortion.
The lens is made of fused silica, a material known for its excellent optical properties, including high transparency, low auto-fluorescence, and high resistance to thermal shock. This makes the SLSQ-25-60N suitable for use in high-performance optical systems that require precision and durability.
The lens's coating is unspecified in the provided data, suggesting that it may be uncoated. This could potentially lead to surface reflections, which could be mitigated by applying an anti-reflective coating. However, the uncoated version may be preferred in certain applications where a specific coating is not required.
The SLSQ-25-60N is designed to operate at a wavelength of 546.1 nm, making it suitable for use in a wide range of applications, from basic optical systems to more complex setups.
