SLB-30-220NIR2 30.0 mm Dia. x -220.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-30-220NIR2 is a Plano-Concave Spherical Lens, 30.0 mm in diameter, with a focal length of -220.0 mm, sourced from OptoSigma. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for near-infrared applications.
The lens is fabricated from n-bk7 schott, a popular material in optical systems due to its excellent optical properties. The lens features a plano-concave geometry, with a thickness of 3mm at the edge and 2mm at the center. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface.
The SLB-30-220NIR2 is equipped with an 'opt ir2' coating on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance within the infrared spectrum, reducing reflection and increasing transmission.
The lens is currently in stock and available for immediate purchase. For more detailed information, including technical specifications and pricing, please refer to the vendor's website using the provided weblink.
