Features
- Cemented Achromatic Doublets Kits
- 14-Piece Mounted Lens or 50-Piece Unmounted Lens Kit
- Storage Cases Included
- AR-Coated Doublets with One of Three Coatings
Thorlabs offers achromatic doublet kits containing either mounted or unmounted optics. The mounted kits (LSB08 Series) contain 14 of our most popular Ø1" cemented achromatic doublets premounted in SM1-compatible lens cells. Unmounted achromatic doublets of varying diameters are included in the 50-piece kits (ESK50 Series).
The most typical application of achromatic doublet lenses is to reduce the chromatic aberration that is symptomatic of spherical lenses as well as to reduce other aberrations such as coma. Other applications of achromatic doublets include the diffraction limited focusing of laser beams and the focusing or imaging of white light within the design wavelength range.
These achromatic doublets are also available individually by visiting our Achromatic Doublet Navigation.
LSB08 Series of Mounted Achromatic Lenses
Our LSB08 kit comes with 14 of our most popular A- (400 - 700 nm), B- (650 - 1050 nm), or C- (1050 - 1620 nm) coated Ø1" achromatic doublets premounted in SM1-compatible (1.035"-40) lens cells. The mounted optics are housed in a plastic case. See the LSB08 Series tab for detailed information on the included optics in each kit.
ESK50 Series of Unmounted Achromatic Lenses
The ESK50-B kit includes 50 of our most popular unmounted achromatic doublets housed in a storage case that makes it convenient to accommodate a growing collection of optics. This kit includes optics with a broadband AR coating for 650 - 1050 nm. Detailed information on the included optics can be found under the ESK50-B tab. The stackable steel cabinet that houses the unmounted achromatic doublets can be combined with other cabinets in our selection of storage cabinets. Alternatively, the storage cabinet can be integrated into our 19" Rack System.

Updated ESK50-B Packaging
Smart Pack Goals
- Reduce Weight of Packaging
- Increase Usage of Recyclable Materials
- Improve Packing Integrity
- Decrease Shipping Costs
Thorlabs' Smart Pack Initiative is aimed at minimizing waste while providing adequate protection for our products. By eliminating any unnecessary packaging, implementing design changes, and utilizing eco-friendly materials, this initiative seeks to reduce the environmental impact of our product packaging.
The updated ESK50-B packaging consists of recycled paper plus minimal foam and plastic wrap. It weighs 83% less than the original packaging. This weight change results in up to a 13.37 kg reduction in travel-based CO2 emissions per year, based on typical product sales.
As we move through our product line, we will indicate re-engineered, eco-friendly packaging with our Smart Pack logo, which can be seen above.
