Review BAUSCH AND LOMB Vintage Binocular Microscope Model

The Bausch & Lomb CTA-8 Binocular Microscope, a classic and highly regarded instrument in the field of microscopy, was first introduced by Bausch & Lomb in the 1940s. Designed for various applications in fields such as education, research, and industrial inspections, this microscope delivers exceptional optical performance and ergonomic features.

The CTA-8 is a binocular microscope, which means it provides two independent eyepieces, allowing for stereoscopic viewing. This depth perception enhances the user's ability to observe and analyze intricate details, making it an ideal choice for applications that require precise observation, such as in biology, medicine, or manufacturing.

The microscope features a 0.85x magnification system, which provides a wide field of view and is suitable for examining larger specimens. The objective lenses range from 2.5x to 1000x, offering a total magnification range of 2.5x to 810x. This versatility enables users to switch between low and high magnifications as needed, making it a versatile instrument for various applications.

The CTA-8's illumination system is equipped with a 12-volt bulb, providing ample and even illumination for specimens. It also features a coarse and fine focus mechanism, allowing users to achieve sharp and precise focus, ensuring optimal observation of the sample.

The microscope's body is constructed from high-quality materials, ensuring durability and stability. The arm and head are adjustable, providing flexibility for users to position the microscope to their preference. The CTA-8 also comes with a built-in Abbe condenser, which optimizes the lighting and increases the resolution and contrast of the image.

The Bausch & Lomb CTA-8 Binocular Microscope is a reliable and high-performing instrument that has stood the test of time. Its classic design, coupled with its exceptional optical and ergonomic features, makes it an excellent choice for researchers, educators, and professionals in various fields who require a versatile and precise microscope for their work.

2. Manual Focus: While the precision focus adjustment is a pro, it can also be a con as it requires manual effort and can be time-consuming.

3. Size and Weight: The microscope is relatively large and heavy, which can make it less portable and more difficult to transport compared to other models.

Details:

The door has a warp in it making necessary to press into place engage the lock, key lock is present. This is a Bausch And Lomb microscope manufactured in 1940. I find it, or a model virtually indistinguishable from referred to as CTA-8. The microscope fits into its case with the binocular head fitting a rack on doors interior.

The holder is not calibrated to measure the motion in either direction. It comes with two pairs of eyepieces: 5X And 10X, three objectives: 3.5X, 10X 44X. The case may have been made for a slightly different model as there is felt-covered stay that swings down but does not engage the head it was apparently designed to do. The mechanism for the adjustment of inter ocular separation operates smoothly.

The case is made of walnut And sturdy finger-jointed construction. I say this because there appears to be a deterioration in image quality at higher powers beyond what one would expect when increasing the magnification. The mirror is of two-sided planar And concave design in pristine condition with no loss silver. The various objective/eyepiece combinations will yield magnifications of 17.5X, 35X, 50X, 100X, 220X, And 440X.

In short, this is a sturdy vintage microscope in good condition And ready for use by students, hobbyists serious investigators alike. I suspect that the microscope was used in a college lab where instruments did not And do to this day always find their way back correct cases. The understate consists of a simple Abbe lens And iris combination, height adjustable via rack pinion. The stage features a spring-loaded slide holder with rack And pinion mechanisms to facilitate both lateral longitudinal motion.

The objectives are made by Spencer, but compatible with this microscope And in excellent condition. It is therefore assumed that any buyer buying or purchasing an item has viewed the listing in its entirety And no further questions regarding. The door of the case has a warp in it, but does lock securely. Please carefully view the photos as they are an integral part of this .

Per division. The condition is quite good, both optically And mechanically. The interior prism system can probably use a gentle cleaning.
