Laser line optics and optical polarization filters

Laser line optics

The Pentaprism is a five-sided prism used to deflect the input beam 90 ° so that the image does not come out upside down. The two reflective surfaces are coated with an anti-reflection coating to reduce a light loss (transmission) since the incidence angles are less than the limiting angles. It is widely used in laser level, leveling, and optical instruments. These prisms deflect the beam at the same angle regardless of its orientation to This makes penta prisms valuable for applications requiring accurate 90 ° deflection without the need to accurately orient the prism. The monolithic design of the penta prism also makes it more stable than a dual mirror system.Hemispherical lenses have good performance in microscopy, endoscopy, fiber optic communications, optical sensors, laser measuring systems, LED especially for high power and ultraviolet LEDs. Hemispheres have much more advantages than silicone lenses and plastic lenses. Alpine Research Optics produces the best laser line optics, laser lenses, and prisms.

Optical polarization filter

An optical polarization filter is a filter consisting of 2 rings in one of them there is a specially processed glass (polarizer), by rotating the ring with polarizing glass, you can adjust the degree of polarization. This filter allows you to remove glare from glass or water when shooting, trapping reflected rays. The filter also allows you to get more saturated images, in which the clouds will be more drawn, the vegetation will look more juicy, here, like with water, the air contains water particles that reflect light, hence the images without a filter are dim, not always blue sky, and «indistinct» clouds.

Using a polarizing filter.
