XUM100 Upright Metallurgical Microscope

The XUM100 is an upright metallurgical microscope with a one-piece frame and a choice of binocular or trinocular observation tubes.

Product Overview

The XUM100 is an upright metallurgical microscope with a one-piece frame and a choice of binocular or trinocular observation tubes. It supports 5X to 100X magnification with infinity-corrected long working distance plan achromatic objectives. The 30° inclined, 360° rotatable tube allows for ergonomic viewing, and the Kohler illumination system provides even field lighting with a field diaphragm. The microscope is configured for reflected light inspection of polished metal surfaces, machined parts and semiconductor wafers.

  • Precision engineering workshops inspecting machined or coated parts

Problems It Solves

  • Fixed-angle observation tubes force operators into awkward postures during long inspections
  • Lack of Kohler illumination causes uneven brightness and glare on reflective surfaces
  • Short working distance objectives cannot accommodate thick or uneven samples
  • No trinocular option prevents simultaneous viewing and image capture during inspection
  • Mechanical stages with high-positioned controls make fine sample movement difficult
  • Inconsistent magnification across objectives due to non-infinity-corrected optics

Technical Features

  • One-piece frame from arm to base for structural rigidity
  • Binocular or trinocular observation tube with 30° inclination and 360° rotation
  • Interpupillary adjustment range 48~75mm with diopter compensation
  • Infinity-corrected optical system with long working distance plan achromatic objectives
  • Kohler illumination with field diaphragm for even, glare-free lighting
  • Mechanical stage with 156x138mm platform and 76x54mm travel range
  • Low-positioned X/Y coaxial control knobs for smooth, precise movement
  • Quadruple or quintuple revolving nosepiece for quick objective switching
  • Reflected light illumination with 12V100W halogen lamp and power box
  • Optional darkfield condensers for surface defect detection on polished metals

Customization Options

  • Choose between binocular or trinocular head with 20/80 light split for camera use
  • Select from quadruple or quintuple revolving nosepiece for objective access
  • Add optional darkfield condensers for surface defect detection
  • Upgrade to 12V50W or 12V100W Osram halogen bulbs for longer life

  • Attach a camera to the trinocular port for image capture and documentation

Comparison With Other Options

XUM100 without trinocular headThe trinocular version adds a 20/80 light split prism so a camera can capture images while the operator views through the eyepieces
XUM100 with quadruple nosepieceThe quintuple nosepiece allows five objectives to be mounted at once, reducing the need to change them during inspection
XUM100 with swing-out condenserThe swing-out condenser allows easy access to the stage for large or thick samples; the Abbe condenser is fixed and provides better alignment

Use Guide

  • Adjust the interpupillary distance to match your eye spacing before focusing
  • Set the field diaphragm to the edge of the field of view to reduce glare
  • Use the 100X objective with immersion oil for maximum resolution on polished surfaces
  • Switch objectives using the inward-facing nosepiece for smooth, stable transitions
  • Position the mechanical stage so the sample is centered before starting inspection
  • Use the low-positioned X/Y knobs for fine, controlled movement during detailed examination
Answers

Frequently Asked Questions

What is the working distance of the 100X objective?

The 100X objective is designed for oil immersion and has a very short working distance; it is not suitable for dry observation

Can I use this microscope for semiconductor wafer inspection?

Yes. The 5X to 100X infinity-corrected objectives and Kohler illumination are suitable for inspecting polished wafers and surface features

Does the trinocular head allow camera use while viewing through the eyepieces?

Yes. The trinocular head splits light 20% to the eyepieces and 80% to the camera port

What type of oil should I use with the 100X objective?

Use immersion oil with a refractive index of 1.515 for best optical performance

Can I use a 6V lamp instead of the 12V lamp?

Yes. The microscope supports 6V20W and 6V30W halogen lamps and bulbs, but the illumination intensity will be lower

Is the stage compatible with large samples?

The standard mechanical stage is 156x138mm; larger stages are not offered in this model
