Triple achromatic lens
PRODUCT CATEGORIES
- Triple achromatic lens is composed of a piece of low refractive index coronal glass and two pieces of high refractive index flint glass. It is usually used to eliminate the axial chromatic aberration of the spherical surface. It is usually used in projection system, imaging system, laser measurement system, etc.
- Triple achromatic lens has infinite conjugate ratio, which is very suitable for focusing and imaging amplification of collimated beams. Achromatic triple glued lens achromatic triple glued lens is the simplest lens used to correct all primary aberrations. These three glued lenses are made by gluing a low refractive index lens between two high refractive index lenses, which can minimize the color difference and have excellent on-axis and off-axis performance.
