Primarily, alignment telescopes (also called "line scopes" or "line of sight" telescopes) are used to establish and maintain principal optical reference lines. In addition, they can generally provide the all-important functions of collimation, autocollimation and autoreflection. Almost all of our alignment telescopes are of the original Keuffel & Esser (K+E) design. These instruments were manufactured and distributed by Cubic Precision before that company joined Brunson Instrument in 1997. At that time, we consolidated our alignment telescope products and adopted the K+E design as our primary product offering.
Our alignment telescopes are made of a very heavy-walled, heat treated, special alloy stainless steel tubing, and concentrically ground inside and out to extremely fine tolerances. Optical systems are precisely installed, and the image is especially bright and clear, having excellent definition. Like all of our instruments, our alignment scopes have the unique ability to prove their accuracy right on the job.

Barrel
All of our alignment telescope barrels meet A.I.A. specifications, and are hardened and ground to assure good stability and accuracy. The outside diameter is 2.2494" to 2.2497" on all instruments except the 381 series, which has a barrel diameter of 1.7494" to 1.7497".
Micrometers
Some alignment telescopes have built-in optical micrometers, others don't. If the instrument has micrometers, precise measurements of lateral displacement from the line of sight (both horizontal and vertical) can be taken. Micrometers are mounted within the barrel. Different models are available with varying resolutions, ranges and measurement units (metric or English). See the list of alignment telescopes for a summary of the various models.
Autoreflection Target
Many of our alignment telescopes have built-in autoreflection targets on the objective (front) end. These paired-line targets are concentric to the line of sight within ±0.001". Three spacings exist (0.008", 0.025", and 0.082") between the paired lines for use at all distances up to 100. (A 0.092" circle target is also included.) The target may be illuminated from the rear by an autocollimation light source.
Bases
Most alignment telescope models may be set up using base models 88-6, 89, 5150 through 5180, and 388 (for the 381 series of smaller-diameter alignment telescopes). Custom mounting hardware is also available on request. Bases are not furnished with the instruments.
Lighting
Illumination is supplied by a low-voltage lamp in order to decrease heat distortion and prevent shock damage. A transformer and cord are supplied to step down from either 110 volt or 220 volt power.
We have over 70 years of experience as one of the worlds premier manufacturers of specialized, industrial, opto-mechanical measuring instruments used by companies such as Boeing, Lockheed, Cessna, Hughes, Space Systems Loral, and others. So it's no wonder that we think we have some precision manufacturing talents to offer! As a third generation family business, we have a strong commitment to quality craftsmanship and customer service.
