Cylinder Lenses are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylindrical Lenses have a single cylindrical surface that causes incoming light to be focused in only a single dimension, stretching the image,These cylindrical lenses are designed for applications requiring one-dimensional shaping of a light source.
We are offered plano-concave or plano-convex, bi-convex, biconcave, achromatic, triplet lens, rod lenswith N-BK7 glass, UV Fused Silica, or CaF2, Sapphire, and coating or not upon request

1. The flexibility of pbt plastic is very good and it is resistant to falling and has strong anti-brittle performance.
Plastic net tells the characteristics of pbt plastic
Pbt plastic is also a material mainly divided into butyl phthalate. Because the English abbreviation of butyl phthalate is pbt, it is called pbt plastic , which is a thermoplastic material. Today, China Plastics Network - Jiuzhi Plastics Network takes everyone to understand the characteristics of pbt plastic, as follows:

2, this plastic is not flammable like ordinary plastic, in addition to non-flammable, it also has self-extinguishing function and electrical properties are relatively high in this thermoplastic plastic, so the price is more expensive in plastics.
3, water absorption performance is very low, ordinary plastics are easy to change in water with higher temperature, this pbt plastic can not be used for a long time without this problem, but also maintain good performance.
4, the surface is very smooth, so the friction coefficient is more convenient to use, but also because its friction coefficient is small, so it is used in the use of relatively large friction loss.
5, just mentioned above, this plastic has strong stability as long as it is formed, and it is a high-quality plastic material in terms of dimensional accuracy. Even in long-term chemicals, it can remain as it is, except for some strong acids and bases.
6, a lot of plastics are of enhanced quality, this pbt is not the opposite of its fluidity is very good after the molding process works well. The polymer fusion technology is used to satisfy the properties of some alloys that require polymers.
