Achromatic Lenses
Frequently asked questions
Here are some common questions about achromatic lens.
It combines two optical elements with different dispersion properties
The chromatic error of one lens is compensated by the other
This brings two wavelengths into the same focal point
No
They correct chromatic aberration and reduce spherical aberration
Other aberrations (coma, astigmatism) may still remain
Cemented Doublet:
- Compact design
- Lower reflection loss
- More cost-effective
Air-Spaced Doublet:
- Better thermal stability
- More design flexibility
Consider:
- Required wavelength range (UV, VIS, NIR)
- Focal length and working distance
- Application type (imaging, laser, measurement)
- Yes
- Lenses can be customized based on:
- Material selection
- Coating type
- Diameter and focal length
- Specific system requirements
