The LAS-BT is a Bench-Top 96 lb downscaled version of the standard  600 lb LAS, at a lower price tag, designed for cementing doublets or aligning lenses during small lens-assemblies.

Same easy operation for a technician or trainee to learn in just a couple of hours. Does not require an engineer to run it.

• Non-contact measurement and alignment of centration and tilt with instant results.
• Optical assembly, doublet cementing, inspection of optical and mechanical runout to under 5 micron TIR.
• Compact Bench-Top design requires little space
• Stable 50 pound granite base, 100 mm Air-Bearing (ABS) with vacuum trough center.
• Repeatable measurements for lens radii from 2 mm to infinity, with same objective.
• Rigid vertical column with precision linear-stage focusing.
• Clean room compatible, 16 inch vertical linear positioning rail, standard oil-free venture vacuum pump.
• Easy, fast setup in existing assembly room
• Size: 17x18x33 inch. Weight: 96lbs
• Utilities: 120V, compressed air 80PSI
• Options: Linear slide or encoder, Motorized ABS, Angular encoder

Packed with high performance features:

The “LAS-BT” is designed for fast setup and ease of use. The visible diode laser beam measures tilt smaller then 5 arc seconds by reflection from a short radii of curvature of ±2 mm to infinity, and provides centration accuracy (linear) of less than 5 microns. The compact optical sensing head moves easily on a firm, vertical column using an economic, manual Z-drive, and utilizable on any lens surface, spherical to cylindrical for cementing doublets, mounting glass and crystal optical components, or potting subassemblies and assembling entire lens systems. Brass mounting base and chucks are available to accommodate lenses from 2 mm to 100mm, and the system handles coated and uncoated lenses with equal ease.  

Other LAS models: OAT offers Ultra Precision systems for 0.2 um centration and Z-axis zone over 1.5m on the “LAS-UP” model. The “LAS-LS” Lithography model is for diameters over 650mm.
