Product Description

General Introduction: Raytek's uncoated n-bk7 precision planoconvex lens is polished with a master test plate to achieve strict tolerances and minimize wavefront distortion in harsh laser electro-optic focusing 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: Uncoated N-BK7 Plano-Convex Lenses
Alias: Uncoated N-BK7 Plano-Convex Lenses, Uncoated Plano-convex Lens, Uncoated lens, Uncoated N-BK7 Lens, Uncoated Plano-convex mirrors, Uncoated Lenses,etc

Main Applying: Camera, film production, projection equipment, laser photoelectric focusing, etc

Products Highlights:
Our uncoated precision planoconvex lenses are polished to a strict tolerance and use a master test plate to ensure minimal wavefront distortion to meet the stringent requirements of laser electro-optic focusing applications. Strict surface quality tolerance minimizes scattering and unnecessary diffraction effects. Our standard precision lens has a surface quality of 40-20 scratch pitting and a surface power of 1.5λ. We also offer economical lenses with 60-40 scratch pitting surface quality to provide superior performance at a lower price.
Advantages of uncoated lens
The uncoated lenses are used in optical systems and equipment, mainly because they have a very wide wavelength range, high damage threshold ratio, and no need to be coated, so they are always cheaper than coated lenses. In addition, the uncoated lens makes the image in the camera look more "retro", which is becoming more and more popular in cinema film production.
