Lenses are the most basic optical component. Glass
Perfection provides a lot of different types of off
the shelf lenses with the material BKY, fused silica
etc. Special requirements can be answered and designed
by Glass Perfection engineers upon request.
Function
It collects light from a source and refracts that light
to form a usable image light itself or it may be an
illuminated object.
Applications
Focusing
columating
Imaging
The simple lens is a single optical element that refracts
inadent light to form an image. The most common simple
lens forms are Plano-convex lenses, Double-convex lenses,
Plano-concave lenses and Double-concave lenses. Each
lense has a certain degree of power (o)
o = (n-1)(1/R1-1/R2)
Where:
o = Lens power (=1/focal length)
n = index of refraction of the lens material
R1 = radius of surface 1 of lens
R2 = radius of surface 2 of lens
(for double-convex lenses, R2 is negative)
Lens Markers Formula
o = 1 = (n-1)(1- 1) + (n-1) t
f R1 R2 n R1R2
Where:
t=lens thickness |
