BK7 Ball lenses and Half Ball Lenses
Fused Silica Ball and Half-Ball Lenses
Ball Lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Ball Lenses feature short back focal lengths to minimize the distance needed from the Ball Lens to the optical fiber. Uni Optics offers a variety of Ball Lenses in a range of substrates for performance in the ultraviolet to the NIR.
Micro-components-Rod Lenses
Micro Sizes Rod Lens
Rod Lenses are used for fiber coupling and laser diode beam shaping, lenses with a 0mm working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well. UNI Optics can provide the size from Φ1～Φ15mm, quantity price and custom sizes, including variations in polished/ground surfaces, are available to OEM customers upon request.
Achromatic Lenses with AR coating at visible range
Broadband AR Coated Achromatic Lenses(Doublet Lenses)
Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. Achromatic Lenses, which are often designed by either cementing two elements together or mounting the two elements in a housing, create smaller spot sizes than comparable singlet lenses.
Optical glass Meniscus Lenses
Positive Meniscus Lenses And Negative Meniscus Lenses
The Positive Meniscus Lenses are a convex-concave lens, but it is thicker at the center than at the edges. They are felt polished and are used universally in the ophthalmic industry where convention dictates that lens power be specified in Diopters.

The Negative Meniscus Lenses are a convex-concave lens, but it is thinner at the center than at the edges. Otherwise description is similar to Plano Concave lenses.
Crown Glass Double-Convex Lenses
MgF2 Coated Double-Convex (DCX) Lenses
Double Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. DCV Lenses are used in a range of industries or applications. Uni-Optics offers Double Convex lenses with a variety of coating options.
BK7 Plano-Convex Lenses
UV Fused Silica Plano-Convex (PCX) Lenses
A Plano-Convex (PCX) lens causes light to focus to a point,it has a positive focal length,which is ideal for light collimation or for focusing applications utilizing monochromatic illumination, in a range of industries. Uni-Optics offers PCX lenses with a variety of coating options.
Double-Concave Lenses with AR coating
VIS-NIR Coated Double-Concave (DCV) Lenses
Double Concave Lenses are used in beam expansion, image reduction, or light projection applications. These lenses are also ideal for expanding the focal length of an optical system. Double Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths. Uni-Optics offers Double Concave lenses with a variety of coating options.
Plano-Concave Lenses
Optical Glass Plano-Concave Lenses
Plano Concave Lenses are ideal for beam expansion, light projection, or for expanding an optical system's focal length. Plano Concave Lenses, which have one concave surface, are Optical Lenses with negative focal lengths. PCV Lenses should be shaped with the plano, or flat, surface towards the desired focal plane. PCV Lenses are ideal for use in a range of applications or industries. Uni-Optics offers PCV lenses with a variety of coating options.

Metallic Coated Mirrors
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.
