KPC028AR.33 25.4 mm Dia. x -200 mm FL; Plano-Concave Lens Laser V-Coat 1064nm
This KPC028AR.33 optical lens, sourced from MKS/Newport, is a plano-concave spherical lens designed for use with a 25.4 mm diameter and a focal length of -200 mm. The lens is made from the popular N-BK7 material, a borosilicate crown glass known for its excellent optical properties and versatility.
The lens features a plano-concave geometry, meaning one side is flat while the other is curved inward. This design is particularly useful for applications requiring a reduction in beam diameter or a diverging beam. The lens has an edge thickness of 3.13 mm and a center thickness of 2.5 mm, ensuring durability and resistance to damage.
The KPC028AR.33 lens is coated with Newport's AR-33 coating on both the front and back surfaces. This coating is specifically designed for use with a 1064 nm wavelength, reducing reflection and improving transmission. The coating ensures optimal performance in laser applications, making this lens an excellent choice for users working with this specific wavelength.
The lens is currently in stock and available for immediate purchase. For more detailed information, please refer to the vendor's website at https://www.newport.com/f/ar33-n-bk7-plano-concave-lenses.
