Microscopes plus accessories:
We can supply the whole range from
Meiji Techno MT5300 biological microscope
Meiji Techno, offers microscopes in many different areas:
Stereo Zoom with the world renowned EMZ line,or the RZ line with common main objective and 10:1 zoom ratio, professional biological and metallurgical scopes for many different applications, including polarization and fluorescent illumination. If you need an inverted microscope Meiji’s IM7000 series should be your first choice.

A current pricelist in pdf format - some 186 pages - is available, just drop us a note.


Motic trinocular GEM scope with darkfield and incidident fluorescent illuminationMotic
offers Stereo Zoom scopes, image shows trinocular GEM microscope, upright and inverted biological microscopes, metallurgical microscopes for industrial appllications, PSM-1000, see also below under industrial scopes, CMOS and CCD cameras, and much more. -

Mitutoyo microscopes and related parts are all listed under Industrial Microscopes, see below.

Microscope Objectives
are the most important element of every microscope.
We carry these lines:
Meiji Techno Plan Epi Objective Brightfield / Darkfield 100X objective
Meiji Techno
Mostly infinity corrected DIN objectives but also some special 26 mm thread (Mitutoyo) brightfield / darkfield objectives, see 100X version at left. And 160 mm tube length objectives are still available as well. All objectives are designed for Meiji’s various biological and metallurgical microscope lines but often used on other manufacturers scopes, sometimes with significant performance improvement.


Mitutoyo M Plan APO NUV BF 100X WD 11.0mm objectiveMitutoyo
dominates still when you need NUV, UV, or NIR objectives beyond 50X. And some customers demand Mitutoyo, even when there are lots of alternatives. But there are some altenatives, see next paragraph.


Plan APO 50X NA=0.70 WD=3.5 mm Metallurgical NUV objectiveNUV objectives from 20X to 50X manufactured in Asia, shown at left is a version with high NA of 0.70 and 3.5 mm working distance, offered by Mitutoyo at a significantly higher price. If you need more WD then a 50X with 14.81 mm is close to the standard Mitutoyo NUV 50X and NA of 0.43 is marginally better at $1200 less. See this page set for more details.


Motic Plan Fluar Objective 100X (Oil)Motic:
Biological objectives for BA400 adhere to DIN standard,Motic Plan APO ELWD 20x NA=0.420 WD=20 mm Metallurgical objective, parfocal distance adjustable Infinity corrected, 0.17 mm cover glass correction. Fluar 100X objective shown on left side.
ELWD and ULWD lines ranging from 2X to 100X with or without fine adjustment of parfocal length. 20X ELWD objective with parfocal adjustment shown at right.
Plan APO LWD 50X NIR objective NA=0.42 WD=19 mm Metallurgical objectiveNIR objectives in 20X and 50X are available. Image at left shows the 50X version,
more details at bottom of this page.




Optem 10X LWD High Resolution objective with high NA
manufactures standard LWD objectives from 5X to 50X. Or if you need high NA for your project then these High Resolution objectives are very attractive. On zoom scopes lower magnification (2X - 20X) objectives create a need for high Numerical Aperture or resolution will suffer.
This is a unque objective, originally created to accomodate the needs of Optem’s Azoom probe station microscopes.

Plan APO 150x NA=0.60 WD=4.4 mm Metallurgical objectiveComplete set of Mitutoyo style LWD objectives for visible range: Magnifications from 1X to 500X are available, some are unique and not manufactured anywhere else. Image at left shows a 150X objective with NA of  0.60. If you need magnification beyond 100X and can tolerate a working distance of 4.4 mm then take a close look.
page links to more objectives with long working distance but not manufactured by Mitutoyo. Some are similar to the Mitutoyo SL line. LWD DIN objectives from 2.5X to 100X are offered as well, easily usable on a scope with 200 mm infinity lens. The working distance is unsurprisingly not on par with Mitutoyo style objectives but a 50X with WD of 7.9 mm and NA of 0.55 is usable with many applications and will be easy on your budget.

M Plan APO 20x NA=0.42 WD=20.2 mm Metallurgical NIR objective with 3 mm coverglass correctionLWD objectives, similar to Mitutoyo, NIR transmissive with DIN threading come and adapter to 26 mm threads. 20X and 50X are available with 3 mm cover glass correction,
OKH line is available in NIR, see image at right, or visible range versions at attractive pricing.


Industrial Microscopes
Mitutoyo Finescope FS70Mitutoyo
Mitutoyo’s FS70 is an industrial microscope for inspection, testing, laser repair, and ablation.
Motic PSM-1000 assembly covers visible and laser operations with one main bodyMotic’s
PSM-1000 assembly covers visible and laser operations with one main body, making it significantly more economically, compared with Mitutoyo’s approach of 3 different bodies, depending on spectrum.

Meiji FU1000 with quintuple 26 mm threaded nosepiece, trinocular head, fiberoptic illuminnationMeiji Techno
offers with the FU1000 and newer FU3050 series focus blocks an attractive way to build a custom compound microscope, at comparatively low cost..Zoom Kits with 6.5 zoom range and 20X objectives
Zoom Scope with a 6.5X zoom range shares some 60% of the assembly with the compound scope above. You can switch between compound and zoom in about a minute.
