QUESTAR QM-1 PHOTO-VISUAL LONG DISTANCE MICROSCOPE
The Questar QM-1 Long Distance Microscope is the innovative instrument for which the Questar Corporation received an "Industrial Research Magazine" award
as one of the 100 most significant new technical products of the year in 1983. This was the first of a series of compact and lightweight long-distance
microscopes developed by us which for the first time allowed images to be made of microscopic subjects in enclosures, in hostile environments, in
process and on-line. Microscopic resolution could be achieved from a longer distance without cluttering the work area with instrumentation.
Right: QM-1 Long Distance Microscope, Long Mount variant with lens cover aside (114,018 bytes). The QM-1 Long Distance Microscope are lightweight and offer superb performance and at reasonable cost for general industrial or research applications or for teaching. With a working range of 56cm (22 inches) to 152cm (66 inches), a 30 to 1 variability in field of view, and remarkable depth of field, linearity and chromatic correction it is an indispensable tool for a wide variety of laboratory and industrial applications. The QM-1 includes two selectable ports so it is compatible with both Questar Brandon 1.25" Eyepieces or many third party standard slip-fit eyepieces, and with with 35mm SLR and with common digital and video camera formats. These are compact round barrel instruments provided with a precision machined aluminum mounting ring, this ring is provided with a selection of tapped and threaded holes so that the instrument may be supported on steady fixtures or built into another device, or the instrument may be installed onto any of Questar's line of fixturing and transit/measurement positioning stages. The standard QM-1 'Short Mount" Long Distance Microscope optical tube assembly is available as shown below right, its standard configuration. The short mount instruments are the lightest of the group and feature a rotatable control box which allows viewing or diverting the light cone, or attaching a co-axial light source from either side of the microscope. This may be used effectively even when attached onto a suitable photographic field tripod. Or, for applications that require the most rigid bore sighting accuracy (for measuring, precision alignment, etc.), then we offer the QM-1 Long Mount arrangement. The long mount instruments are more rugged and feature a mounting pad which extends the length of the barrel. The standard BK7/MgFl2 Optics Group provides transmission spanning 350 to 2000 nm. While the optional Fused Silica/MgFl2 Optics Group provides Transmission Range spanning 180 to 4000 nm. |
