An automated system for selecting optical apparatus compares a set of user specifications with the optical characteristics of a plurality of standard optical components, and automatically chooses a combination of the components forming the closest match to the user's requirements. The method is performed using a programmed computer which may be remotely interfaced with the user via the internet. The user inputs the specification into the computer using a standardized input table. The user may optionally specify that the system be designed using a particular product line or family of standard products. If a system exactly matching the customer's specifications cannot be found, two systems are suggested that bracket the customer's stated requirements.

Automated selection of optical systems

A multi-objective optical instrument, such as a microscope, has a photocell disposed in the optical path so as to effectively detect the intensity of light being transmitted by an illuminator to a receptor plane, such as defined by an operator's eyes. The light detected by the photocell is compared against a preset level of light. The intensity of the illumination would be adjusted automatically to a minimum level when the carrier is rotated and to a preselected level when an objective is in place for viewing. An electrical switch is cooperatively mounted to the rotatable objective carrier and detects rotation of the carrier to control the flow of current to the illuminator.

Automatic illumination control for multi-objective optical instruments

A specimen mount for a microscope holds a fiber optic cable so that the end of the cable may be examined. The mount is rotatable to angularly displace the cable end being examined.
