About Labrum Optical Engineering
Labrum Optical Engineering's founder holds 10 U.S. patents for designs, devices, and techniques in the optical engineering sciences. He has also created sophisticated computer programs to simulate and optimize optical/mechanical systems. In addition, he is the author of over 40 proposals, technical reports, and "white papers" for private industry, government, and professional journals.
Labrum Optical Engineering has its own computers and software. We don't need to lease expensive hardware or software, and the savings are passed on to our clients.
Along with the savings, you get exceptional capability and quality. We have several hundred proven optical designs in our data base. With Labrum Optical Engineering, you can avoid the risk involved in using undocumented, off-the-shelf optics that produce undocumented results. Custom-designed optics by Labrum Optical Engineering can ctually be less expensive (in quantities of 50 items or more) than off-the-shelf optics offered by some "ready-made" suppliers.
All our designs are fully documented and become the property of the client. Documentation includes:
Manufacturing part drawings, with tolerances
Ray fan plots
MTF Diagrams
Field curvature
Through focus spot diagrams
For some clients, experience, innovation, and quality are not enough; they also need fast turn-a-round time. Labrum Optical Engineering will work with you, step by step, to provide our services on time and on budget.
Perhaps you already have an excellent, in-house design group that needs little more than an outside opinion from time to time. Labrum Optical Engineering is available. Perhaps you have an extra heavy workload right now that requires an extra hand. Labrum Optical Engineering is available.
On-site customer-tailored, professional seminars to upgrade the skills of management, engineering, and technical personnel in the optical engineering sciences.
Joseph Labrum, our president, is a consulting optics engineer with 25 years of in-depth experience in solving a wide spectrum of optical engineering problems.
Complex laser
systems for electronic signal processing. Our signal processing systems have
included acousto-optics (Bragg cell) and Fourier Transform optics to perform
real-time spatial filtering.
Numerous photographic imaging lenses and complex photographic relay imaging systems.
Color-corrected underwater viewing port and underwater field of view correcting lens for the deep submersible rescue vehicle (DSRV).
Color-separation optics and lensing for live video, high-speed video, and tele-cine (film), broadcast-quality color TV cameras.
Precision colorimetry using the CIE chromaticity measurement and display system.
Short-pulsed, UV, N2 laser microscope to measure the size and velocity of high speed aerosol particles 10 microns in diameter traveling 10 meters/second.
Numerous additional direct vision microscopes for specialized use in optical research and development. These microscopes were designed to measure the image quality (MTF) and field curvature of various imaging systems.
A series of microscopes with ultra long working distances.
These microsopes are sometimes referrd to as close focusing telescopes.
These microscopes are useful in alignment of optical components in complex, multi-component, optical assemblies.
Ultra-high performance photo-detection arrays with a measured dynamic range exceeding 60 dB (1,000,000:1).
Low-noise, high-speed, photo-detection circuits.
Optical heterodyne detection

Extensive experience in the speckle problems of coherent (laser) imaging systems. Labrum Optical Engineering has unique techniques to reduce speckle and improve resolution.
Two-element, cemented, diffraction limited, F#3.9 collimating and/or focusing lenses.
Custom spectrometers to determine transmission, absorption, and reflection of various materials in the near UV, visible, and near IR portions of the optical spectrum.
Custom spectroscopes for analysis of multi-spectral line mixed gas lasers in real time.
Non-contract optical metrology systems capable of 0.0002" measurement accuracy.
Scanning and non-scanning metrology system design.
High performance lighting instruments for theatre applications; and high intensity, miniature, under-water lighting systems.
Custom parabolic, elliptical, and spherical reflector designs for special lighting applications.
High performance, long distance (10 km), broadband (1 GHz), single-mode, analog (QPSK), fiber-optic communications link.
Optical wavelength multiplexing and demultiplexing.
Helmet-mounted sights and heads-up display concepts.
Non-contract methods to determine the three-axis attitude of helmets used in headsup display and sighting systems which yield a 10X accuracy improvement over existing technology.
