TM-250 Miniature CCD Camera

Operation Manual

1 Introduction

1.1 Product Description

The TM-250 is an inexpensive, high-quality camera that meets a variety of application requirements.

Featuring an advanced Hyper-HAD

interline transfer 1/2" CCD imager, this miniaturized high-

resolution camera offers many standard and optional features at a very affordable price. A CCIR-format

model, the TM-260, is also available.

1.2 Features

•

Variable electronic shutter and random CCD integration

The substrate drain-type shutter mechanism provides a superb picture at various speeds without

smearing. The electronic shutter rate can be externally adjusted, from 1/60 to 1/10,000 (1/29,100 in

some operating modes) in discrete steps, via a manually controlled DIP switch on the back panel.

•

Miniaturized and lightweight

The use of a CCD image sensor in the video camera module and the development of special mini

C-mount lenses allow the TM-250 to be compact, lightweight, robust, and small enough to operate

just like a remoted head.

•

High sensitivity

The TM-250 camera is one of the most low-light sensitive 1/2" CCD cameras available today. This

feature is especially important when using the faster shutter speeds. The CCD detects images into

the near-infrared spectrum. It requires only 1.0 lux of minimum illumination and 0.5 lux minimum

illumination at maximum gain. In general, this allows the use of a higher lens F-value while

providing a greater ﬁeld depth and sharper images.

•

Low lag/high resistance to image burning
