Product details
Bi concave lens is a specific type of concave lens where both surfaces curve inward( like the inside of a bowl).it's most common shape for simple diverging lens.
UV fused silica bi concave lens have two curved surfaces and a negative focal length, it's similar to Plano concave(PCV) lens, but it has one concave surface.
Bi concave lens also called Double-concave lenses,used to divergent light, which is why it's also called a diverging lens.
Key Features
Shape: thinner in the middle and thicker at the edges
Fuction:causes parallel light rays to diverge (spread out)
Image: always forms a virtual, upright, and small image
Common Uses
Correcting myopia(nearsightedness):used in eyeglasses to help focus light correctly on the retina
Optical instruments: often used in combination with other lenses in telescopes, microscopes, and cameras to adjust the path of light
Laser Beams:used to expand laser beams.
Flashlights: sometimes used in combination with other lenses to control the spread of light
