Thomson Lab Services has a complete range of optical microscopes for inspection and documentation over the full range of magnification – ranging from objects the size of a building to the smallest details which can be observed using light on the surface of a semiconductor integrated circuit (IC).   Output options include color prints, high-resolution digital photographs, digital video files and lower resolution image files for e-mail and electronic communication.    Macro Photography: High resolution, 5MB color digital photographs with a range of wide-angle to over three-power magnification. Illumination can be direct, indirect, diffused, polarized and UV.    Stereo Microscope:  Zeiss SV11 stereomicroscope provides high resolution and documentation over a range of magnification from X3 to X1000, with a range of illumination (coaxial, bifurcated, ring and polarized).  A stereomicroscope has a longer working distance and depth of field than a compound microscope.  The oblique viewing microscope allows viewing of PCB board components from the side, in any direction, for inspection of component mounting and soldering.  This is ideal for surface mounted devices.  Eight additional stereomicroscopes provide lower power magnification for inspection, soldering and fixturing.              Compound Microscope:  Four compound microscope provide inspection and documentation over the range of magnification of X20 to over X2000, the limits of practical resolution for white light optical microscopes with long working distance lens. Illumination options are bright field, dark field, polarized, dynamic interference contrast and transmitted light. The limits of sample size and height are several inches maximum.          Compound inverted metallurgical microscopes enable direct inspection of metallurgical cross-sections and flat specimens.   Confocal Microscope: An option of the Reichert TIC Polycon, improves practical resolution to over X3000 and reduces out of focus background images.  Oil or water emersion short working distance lens will improve resolution by a third for flat samples which can tolerate the emersion media.   Scanning Laser Microscope (SLM):  Zeiss LSM310 scanning laser microscope has a practical magnification of over X5000, the SLM can provide composite image of multiple scans of the laser, at different focus depths. Exceeding the extreme depth of field limitation of high power optical microscopes.  The silicon die of an IC is transparent to the LSM310’s IR laser, which allows imaging the surface of an IC from the backside.   Instrumentation Details:   Zeiss Stemi SV11 - Optical Stereo Microscope Ø Optical Magnification from 4 to 200+ times (<1000 times digital) Ø Multiple illumination modes; coaxial, bifurcated, ring, diffused and polarized Ø Images are available as networked digital files, real time video display and digital prints.   REICHERT TIC POLYCON – Optical Compound & Confocal Microscope Magnification Range: Ø200x – 3000x, visual image (Up to 7500x, on 13 inch monitor) Motorized nosepiece and diaphragm ØViewing modes: Brightfield .
