K9 plano convex spherical lens can see the transmittance of near infrared (350-2000nm).
H-K9L (N-BK7) is an optical glass commonly used in the preparation of optical elements.
The collimated beam can converge on the rear focus, or the point light source can be changed into a collimated beam.
Plano convex lenses are ideal for focusing parallel rays at one point. These lenses can be used in a variety of applications. They have proven focal lengths and have near optimal shapes for infinite and finite conjugate applications. The plano convex lens can focus the collimated beam on the back focus, or turn the point light source into a collimated beam

The plane convex cylindrical lens will focus the incident light on the line with positive focal length. It is composed of a plane and a convex cylinder. It is often used to focus parallel or divergent beams on the line or change the aspect ratio of the image. The flat concave cylindrical lens is composed of a plane and a concave cylinder, and its focal length is negative. It is often used to focus parallel or divergent beams on the line or change the aspect ratio of the image. Borisun optics provides cylindrical lenses without coating and coated with antireflection film. Antireflective film options include UV, VIS, NIR, and SWIR. Germanium, silicon or zinc selenide substrates are suitable for infrared applications, while fused quartz is suitable for ultraviolet applications.

Plano Convex or Concave Square Cylindrical Cylinder Lens
Cylinder Lenses are offered in both plano-concave and plano-convex configurations, they are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylinder Lenses are available with positive or negative focal lengths, they are used for the optics, lasers, medical science, electronics, tele-communication and others.
1. Cylindrical lens with its circumference surface polished.
2. Applicable for laser focusing into a line, changing beam shape into sheet-shape, or irradiating at a distance with elongated line
3. Focal length shortened by reducing the rod lense diameter compared to cylindrical lenses
4. Distortion-free, flexion-free, straight line gainable when projection was made at a distance, by precised process and polishing.
5. Suitable for collecting large sum of light into sensor by putting it right in front of line sensor
