AERIAL PHOTO INTERPRETATION STATIONS

1. Bausch and Lomb Aerial Photo Interpretation Station Model 500 with a modified Bausch and Lomb HFO-4 light table or a Richards HFO-500 light table. The Model 500 has a magnification range of up to 297X, resolution of 800 lines per mm, mono viewing capability and the capacity to match two photographs taken at a scale differential of 6 to 1. It is the premier image analysis system in the world. The optical package consists of a Zoom 500 body with stereo rhomboid arms, 1X (or 3X) stereo attachment lenses and 10X (or 15X) eyepieces with eyeguards. The Model 500 is available in two different versions. The first is a Model 500 without a video adapter and incapable of accepting one. The second has an optical package installed that allows the operator to use a video camera and monitor.

 

 
 
 



2. Bausch and Lomb Aerial Photo Interpretation Station Model 240. The Model 240, long the industry standard until the development of the Model 500, has a magnification range of up to 120X, resolution of 400 lines per mm, mono viewing capability and the capacity to match two photographs taken at a scale differential of 4 to 1. The optical package consists of a Zoom 240 pod with stereo rhomboid arms, 2X stereo attachment lenses and 10X (or 20X) eyepieces with eyeguards. Model 240 accessories are also available.

Available as an option with the Model 240 is a special Bausch and Lomb Dual Power Measuring Macroscope that can be mounted on the same light table. This macroscope has a high precision Filar micrometer eyepiece that allows the operator to measure distances on the photograph along both the vertical and horizontal axis.

LIGHT TABLES

The first is the Richards HFO-500. This table features an adjustable light intensity spotlight of up to 80,000 ft. lamberts that automatically follows the path of the stereo rhomboid arms as they scan over the transparency. This is the second generation light table for the B&L Model 500 that Richards built. It differs from the third and fourth generation tables mainly in that the newer tables have a more intense background light and the spotlight can be moved out of the way to make it easier for the operator to use the background lighting. The HFO-500 has less intense background lighting and only on the left hand side of the table. This table, then, is ideal for operators who mainly rely on the high intensity spotlights as a light source and only occasionally make use of low intensity background lighting.

The second choice is a modified Bausch and Lomb Model HFO-4 light table. This table is a late generation light table that like the standard HFO-4 has 100,000 foot lamberts high intensity spotlights, full background lighting, and magnetically rather than mechanically controlled spot lights. The modified HFO-4 is placed on a photo interpreter's desk on wheels rather than a metal casting on wheels like a standard HFO-4. This allows the operator the convenience of storing film and accessories in several desk drawers. Owing to its design it does not allow the optics to be pushed out of the way in the "storage" position.

The fourth option is a Richards MIM-2030 light table which in addition to strong background lighting has been specially modified to include high intensity spotlights that track the rhomboid arms of the Model 500. Both hand crank and motorized film advance systems are available as accessories with these tables.

The Richards MIM-2 light table has a free standing base with wheels and has a light output of 2200 ft lamberts. Both hand crank and motorized film advance systems are available as accessories with these tables.

The Richards MIM-4 light table has a free standing base with wheels and is considered the best of the MIM series. This light table has greater illumination than the MIM-2, that is to say, 3500 ft. lamberts rather than 2200 ft. lamberts. Both hand crank and motorized film advance systems are available as accessories with these tables.

The Richards MIM 2X9 light table has the same specs as the MIM-4 except that it has an illuminated area large enough for two rolls of film at the same time. This table can also tilt for operator comfort. The table comes with a split or a solid light stage. Both hand crank and motorized film advance systems are available as accessories with these tables.

The Richards HFO-3 light table is among the most advanced that Richards has ever made. The particular tables we have are designed to accept Model 240 optics only. This table has an adjustable light intensity spotlight of up to 80,000 ft. lamberts that automatically follows the path of the stereo rhomboid arms as they scan over the transparency. The Richards HFO-240 high intensity table is also available which is similar in design except that the spotlights track the rhomboid arms mechanically rather than magnetically. Both hand crank and motorized film advance systems are available as accessories with these tables.

The Bausch and Lomb Model 240 light table is a high intensity light table and is the best one ever made by Bausch and Lomb for the 240 optics. It has a light intensity of 90,000 ft. lamberts and uses a different technology than rhomboid arms so that, unlike the Richards tables, most of the stereo pair is at all times exposed to high intensity light and not just the spots below the rhomboid arms. This instrument is a desktop model that must be placed on a desk or table. Hand cranks for advancing roll film are available as accessories with these tables.

MIRROR STEREOSCOPES WITH CASES

This mirror stereoscope is distinguished by the fact that is a scanning mirror stereoscope that allows the operator to scan across the entire 9X9 stereo pair without having to move the photos and thereby going out of stereo. This scope has 4.5X binocular lenses.

Fairchild F-71 mirror stereoscope This is a standard mirror stereoscope with 4X binocular lenses.

Zeiss Model N-2 mirror stereoscope This is a standard mirror stereoscope without binocular lenses.
