Ultra Compact Objective Assemblies
• Shortest and Most Compact Form Factor for an Objective
• Configurable Magnification Using Designated Extension Tubes
• Near Diffraction Limited Resolution
TECHSPEC® Ultra Compact Objective Assemblies are EO’s smallest objective and are nearly the smallest
available in the market in their class of working distance, magnification, and resolution. These objectives are
finite conjugate by design, but achieve similar imaging performance of infinity corrected objectives and do not
require a secondary tube lens to generate an image on the sensor. Designed at 2X magnification, these objectives
are easily configurable to achieve 4X, 5X, 10X, 15X, and 20X magnifications with the addition of longer
extension tubes. The shortest objective length is 10,8 mm for 2X magnification, while the longest objective
length will be roughly 180 mm for 20X magnification. TECHSPEC® Ultra Compact Objective Assemblies base
optics utilize two different numerical apertures and two different focal lengths for four objectives, with two different
working distances of 9,9 mm and 11,4 mm respectively. Note: These objectives are ideal for simple customizations
by adjusting magnification with shorter or longer extension tubes, or to adjust numerical aperture
and working distance by ultimately changing the base optics in the objective which is also easily achievable.

• Lightweight Design with Compact Form Factor
• Configurable Magnification Using Spacers
• Optimized For Long Working Distances
TECHSPEC® Compact Objective Assemblies are designed to reduce the overall
weight and size of an imaging system while maintaining optical performance.
While traditional objective systems typically require long tube lengths and tube
lenses, TECHSPEC® Compact Objective Assemblies optimize each objective to
allow for shorter tube lengths. Standardized 30 mm outer diameters and C-mount
threading ease integration into system assemblies. Magnification can be easily
increased by adding spacers to increase the tube length. Each lens has a broadband
anti-reflection coating to provide even and maximized light transmission in
the visible spectrum.
