International Standard Microscope Objectives
Our full selection of International Standard Microscope Objectives can be used with most major brands of
microscopes that utilize RMS mounting threads. Our product offering features DIN 45 mm standard objectives
with achromatic and semi-plan designs. The achromatic design ensures proper color correction for
broadband white light sources, while semi-plan designs have an added feature to create flatter image field.
International Standard Microscope Objectives include AR coated optics to ensure maximum transmission
and reduce internal reflections in the optical assembly. All 20X to 100X objectives have spring-loaded (retractable)
front ends to prevent slide damage. Note: Oil immersion is recommended for all 100X objectives with
an NA higher than 1,0 (part number #86-834).

Commercial Grade Standard Microscope Objectives
Single Tube DIN Microscopes for Ocular and C-Mount Camera Use
These tube options allow DIN standard objectives to be used directly with either a DIN eyepiece or a CMount
camera. Tubes are the appropriate length for DIN standard. Any DIN objective can be mounted to
either tube. Model #54-869 allows a DIN standard eyepiece to be used with an objective to make an ocular
microscope. Model #54-868 allows the DIN objective to be mounted to a C-Mount camera and achieve a
primary magnification equal to the magnification of the objective. The field of view of the video system is
equal to the sensor size divided by the magnification of the objective. For example, a 4X objective yields a
horizontal field of view of 1,6 mm on a ½” sensor. Objectives and eyepieces are not included with tube assemblies.
C-Mount cameras are available in our Imaging section.
Optional mounting ring allows mounting to a ¼-20 screw. Mounting ring (#52-930) and ¼-20 fine focus
rack and pinion mount (#54-794) are recommended for mounting to boom stands and work station bases.

Designed for a wide variety of applications, our commercial
objectives are provided in both achromatic
and
plan designs. Using DIN standard, 0,7965" (20,1 mm) dia. threads, 36 TPI, 55° Whitworth, these objectives
will fit into most microscope
and spatial
filter assemblies.
Used in conjunction with our C- and T-Mounting
systems they are an ideal solution
for OEM production
use.
