  • description

UNI Optics’s Plano Convex Circular Cylindrical Lens has a convex curvature in the vertical direction and has no curvature in the horizontal direction. They are edged as circular shapes so they can easily be combined with other elements in an optical system.

 

1、How to control the radius correctly?


Uni Optics use the precision templet for processing to make sure the final R value matched your drawings.

 

2、Can you provide the testing report?


Yes. We can offer the actual testing data including Radius, centration, dimensions, surface quality, coating curve, etc..

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.
