Description
Our 22mm achromatic cemented doublet lens consists of two bonded optical glass elements with two glass combinations for custom optical design:
1. Standard BK7/K9 crown + flint glass, cost-effective for general optical systems
2. Premium H-LAF53 & H-ZF7L low-dispersion set for ultra-high resolution imaging
The cemented doublet structure eliminates chromatic aberration and color fringing, delivering far sharper images than single spherical lenses.
Core Advantages
- Custom focal length, multi-layer AR coating and edge blackening available
- Ultra-precision polished surfaces, low stray light and high light transmittance
- Firm optical cement bonding for stable long-term industrial operation
- Custom glass pairs acceptable based on customer technical drawings
Applications
Telescope objectives, machine vision cameras, spectrometers, laser collimation modules, laboratory optical instruments

FAQ
1. What is an achromatic cemented doublet lens used for?
It is a two-piece bonded optical lens mainly designed to correct chromatic aberration. It produces crisp images without obvious color fringes, widely applied in machine vision, spectroscopy, telescopes and precision imaging equipment.
2. What’s the difference between standard and premium glass sets?
- Standard BK7/K9 + flint glass: budget-friendly, suitable for ordinary visible-light instruments.
- Premium H-LAF53 + H-ZF7L: low dispersion with minimal color distortion, ideal for high-end optical devices requiring superior imaging accuracy.
3. Can achromatic doublets correct spherical aberration?
Its primary function is chromatic aberration correction. It performs better than single lenses overall, but aspherical lenses are required to fully remove spherical aberration.
4. Can focal length and coatings be customized?
Yes. We customize focal length, center/edge thickness, edge blackening and full-spectrum multi-layer AR coatings according to your demands.
5. Do you offer sample orders?
Samples, small batches and mass orders are all supported. Every lens undergoes full dimensional and optical performance inspection before delivery.
6. What quality inspections do you carry out for cemented lenses?
Full-process tests include surface finish check, curvature measurement, centration error detection, cement uniformity test and transmittance verification to guarantee stable and consistent optical performance.
