Description
General Introduction: Raytek's 1064nm N-BK7 precision flat convex lens was polished with the main test plate to achieve strict tolerance, thus ensuring the minimum wavefront distortion to meet the harsh application scenarios of laser electro-optical focusing. They have ar.33 broadband antireflection films for 1064nm applications
N-BK7 is an excellent lens material for most visible and near infrared applications. It is the most common borosilicate optical crown glass, which can provide excellent performance and moderate price. Because of its high uniformity, low content of bubbles and inclusions, and easy manufacture, it has become an excellent choice for transmission optical elements. N-BK7 is also relatively hard and has good scratch resistance. The transmission range of BK 7 is 380 to 2100 nm. It is not recommended for temperature sensitive applications such as precision mirrors
Products Name: 1064nm Antireflection Coated N-BK7 Plano Convex Lenses
Alias: 1064nm Antireflection Coated N-BK7 Plano Convex Lenses, 1064nm Coated Plano-convex lens, 1064nm Coated lens, 1064nm Laser line lens, 1064nm Laser line Plano-convex Lens, Laser line plano-convex lens,1064nm K9 Plano-convex Lens,etc
Main Applying: Laser electro-optic focusing application scenarios, Laser protective windows, Laser defense protector, Laser windows, Laser applying.
Products Highlights:
Our precision planoconvex lenses are polished to a strict tolerance to minimize pre wavelet distortion. Strict surface quality tolerance minimizes scattering and unnecessary diffraction effects. These lenses have a surface quality of 40-20 scratch pitting and a surface power with an accuracy of 1.5λ.
1064nm laser line antireflective V film：
Raytek AR.33 laser line V film has the lowest reflectivity at 1064 nm to achieve maximum transmission, while maintaining high durability and high damage resistance. Valuable laser energy can be effectively transmitted through the plano convex lens without loss due to surface reflection and scattering. However, the balance of its superior performance is that it only supports the smallest wavelength range of laser line.
