Chromatic aberration correction
A doublet lens is composed of a positive lens (typically low-dispersion crown glass, such as BK7) and a negative lens (high-dispersion flint glass, such as F2) cemented together.By taking advantage of the difference in Abbe numbers of the two materials and through the rational distribution of optical power, the focus can be made to coincide at two specific wavelengths (such as the F line at 486.1 nm and the C line at 656.3 nm), effectively eliminating axial chromatic aberration.

Telescopes and Astronomical Observations
As an achromatic objective lens, it is widely used in refracting telescopes, focusing red, green, and blue light at the same point, significantly enhancing the sharpness of star points and the clarity of planetary outlines. It is a key component for advanced astronomy enthusiasts to improve image quality.

Microscopy and Endoscopy
In microscopes and medical endoscopes, achromatic doublet lenses can reduce edge purple fringing, enhance color fidelity and detail resolution, and meet the requirements of high-precision imaging.
Collimation and focusing in laser systems
It can efficiently convert point light sources into parallel light beams, suitable for collimating lasers with power above 1.5W, and is widely used in laser processing and measurement systems.
Camera lenses and photographic optics
As the basic unit of a lens group, it is used to suppress color fringing and improve edge image quality, and is commonly found in the design of mid-to-high-end photographic lenses.
Image relay and projection system
Supports image magnification ratio transformation from 1:1 to 4:1, suitable for image transmission systems in the visible light band, such as industrial inspection equipment and projectors.
Confocal 3D imaging
Due to its high lateral and axial resolution, it can be used as an ideal optical component for confocal imaging systems, improving the signal-to-noise ratio and contrast of three-dimensional imaging.

FAQ

Q1: What materials do you offer for spherical lenses?
A: We supply common optical glasses (e.g., BK7, Fused Silica) and selected special glasses — tell us your wavelength and environment and we’ll recommend the best option.

Q2: What tolerances can you hold (surface figure, diameter, centration)?
A: Typical production tolerances are ±0.05 mm for diameter, surface quality 60/40 or better, and centration down to a few arcminutes — tighter specs available on request.

Q3: Do you provide AR/HR coatings?
A: Yes — we offer standard broadband anti-reflection coatings, high-reflection mirrors and custom coating designs tuned to your wavelength range.

Q4: Can you manufacture small sample quantities or prototypes?
A: Absolutely — we handle prototype quantities and low-volume production with short lead times so you can validate designs quickly.

Q5: What is the typical lead time?
A: Lead times depend on specs and quantity; many standard spherical lenses ship within 7–14 business days. Ask for an estimated delivery when you request a quote.

Q6: Do you accept OEM/branding and custom packaging?
A: Yes — we support OEM orders, custom labeling and protective packaging options for sensitive optics.

Q7: How do you handle quality assurance and traceability?
A: Each batch is inspected and accompanied by inspection records; traceability can be provided for production lots on request.

Q8: How can I request a quote or sample?
A: Provide your lens specification (diameter, radius, thickness, material, coating) and target quantity — we’ll respond with a quote and sample options promptly.
