Optika B-510ASB Trinocular phase contrast microscope, 1000x, IOS W-PLAN, Walton and Beckett eyepiece
Optika B-510ASB Trinocular phase contrast microscope, 1000x, IOS W-PLAN, Walton and Beckett eyepiece
€2.258,00 excl. VAT
The Optika B-510ASB is a trinocular phase contrast microscope built around the Walton and Beckett graticule eyepiece used for fiber counting in asbestos analysis. It carries IOS W-PLAN and W-PLAN PH objectives with full Kohler illumination for sharp, contrasted images. The 12.5x additional eyepiece with reticule works alongside the standard 10x pair for calibrated fiber counting fields. The rackless double layer stage and coaxial focusing keep sessions comfortable. It suits laboratories performing phase contrast microscopy fiber counting and other transparent specimen analysis.
Trinocular Phase Contrast Microscope for Fiber Counting and Research
The Optika B-510ASB combines IOS W-PLAN phase contrast objectives with a Walton and Beckett graticule eyepiece, the reference tool for phase contrast microscopy fiber counting. Full Kohler illumination and a rackless stage support precise, repeatable fiber counting fields alongside general phase contrast laboratory work.
- Walton and Beckett graticule eyepiece, 12.5x, for calibrated fiber counting fields
- IOS W-PLAN objectives (4x, 10x, 100x oil) and a W-PLAN PH objective (40x)
- Full Kohler illumination for sharp, contrasted images
- Rackless double layer stage with 78×54 mm moving range
- Suited to phase contrast microscopy fiber counting and research applications
Optika B-510ASB Trinocular Phase Contrast Microscope
The Optika B-510ASB is a trinocular phase contrast microscope from the B-510 series, built around the Walton and Beckett graticule eyepiece used for phase contrast fiber counting.
IOS W-PLAN and W-PLAN PH objectives pair with full Kohler illumination for sharp, high contrast images of transparent, non-stainable specimens.
Walton and Beckett Graticule Eyepiece
The additional 12.5x eyepiece carries a Walton and Beckett reticule, field number 15 mm, giving a calibrated counting field alongside the standard 10x eyepiece pair.
IOS W-PLAN Phase Contrast Objectives
The objective set covers 4x, 10x, 40x PH, and 100x oil PH, plan achromatic corrected with a DIN 45 parfocal distance, giving superior resolution and greater numerical apertures for enhanced contrast.
Full Kohler Illumination
X-LED3 illumination with full Kohler adjustment delivers contrasted and sharp images through the Abbe brightfield / phase contrast condenser, which switches between brightfield and the 40x phase contrast position.
Rackless Double Layer Stage
The 233×147 mm double layer mechanical stage moves on a rackless, belt-driven mechanism with a 78×54 mm X-Y moving range and 0.1 mm vernier scale accuracy.
Ideal Applications
The B-510ASB suits laboratories performing phase contrast microscopy fiber counting and related research.
- Phase contrast microscopy fiber counting
- Occupational hygiene and materials laboratories
- Living cell and microorganism observation
- Microbiology and cytology screening
- Research applications needing calibrated phase contrast fields
