Biconcave aspherical lenses are optical lenses featuring two concave surfaces with an aspherical profile. They are designed to effectively diverge light while reducing spherical aberration compared to traditional spherical lenses. Their optimized shape provides improved beam control and higher optical performance in compact systems.
2. What are the Biconcave Aspherical Lenses used for?
Biconcave aspherical lenses are commonly used in beam expansion, laser shaping, imaging systems, and optical instruments that require precise light divergence. Their ability to minimize optical distortion makes them ideal for high-precision and space-limited applications.
Features:
· Ideal for Beam Expansion and Divergence Control
· Reduced Spherical Aberration for Improved Optical Performance
· Available in a Variety of Sizes and Materials

N-BK7 metallic coated mirror
1、What Metallic Coated types can Uni-Optics supply?
Uni-Optics mainly offers four coating types, including:
1) UV Enhanced Aluminum : Ravg > 85% from 250nm to 400nm
2) Protected Aluminum: Ravg > 87% from 400nm to 800nm
3) Protected Silver: Ravg > 95% from 400nm to 20um
4) Protected Gold: Ravg > 98% from 650nm to 16um
2、What are the features of Metallic coated mirror?
Metallic coated mirror have many key features below:
Wide spectral range
Not sensitive to the incidence angle and polarization state
Low cost
Non-durable
Relatively low reflectance
Low laser damage threshold
3、What UNI Optics can do for you?
Common Specifications:
Substrate Materials: N-BK7, Fused silica, Pyrex；Float glass
Dimensional tolerance: +/-0.1mm
Surface quality: 60-40
Parallelism: 3’
Flatness: λ/4 per 25mm@633nm
Bevel: Protective
One surface: Polished and Metallic coating
The other surface: Fine ground
Note: Aluminum is the most widely used metal reflection film, from near UV to near IR, have high reflectivity, and with low cost. Silver has higher reflectivity in the visible and near infrared wavelength than the aluminum film, but the silver in the air will be rapid oxidation, color darkening, makes the film performance and firmness declined rapidly. Gold film has a good consistency with high reflectivity in the near, middle and far infrared range, can control the thermal radiation effectively, but it is relatively soft, easy bruising, and should be paid very close attention to clean, and the cost is very high.
