The RH-400 (Petrel) radiation tolerant color camera system uses a special control unit in conjunction with a high-powered LED illuminator to provide color pictures from a high radiation tolerant mono-chrome camera. Click here for the black & white version of the RH-400 underwater camera. The high rad underwater camera functions best in relatively low levels of ambient light, however good results are obtained in bright conditions up to 850 lux.

To assist in the initial deployment of the RH-400 underwater camera, the RGB light ring may be turned off, enabling a standard monochrome mode for ease of locating the scene. The monochrome mode makes it easier to focus the lens. The color mode can then be selected to allow detailed examination and recording of the scene in full color.

A digital video (DV) output is available, as well as the standard video signals, allowing the user to feed the signal into a computer equipped with a “Firewire” port, (IEEE1394), and suitable software. In this way, video sequences or individual frames may be captured for later examination.

The Diakont D-40 radiation tolerant camera is one of the most sophisticated and powerful underwater inspection cameras on the market. The small diameter of this camera allows use for under core plate inspection as well as other inspections necessary in confined spaces. Utilizing the wide range of intechangeable viewing heads and lenses for various underwater inspection tasks extends the camera capabilities.

This Diakont D-40 underwater camera is the latest solution for rad hardened split head camera technology. The design includes non-browning optical components and remotely located electronics for greater radiation tolerance. The lens is made of non-browning glass, which withstands the irradiated dose of 200 MRad with no degradation of optical performance.

The high radiation tolerant Diakont D-40 split head underwater camera provides state of art capabilities while satisfying stringent quality standards. All stages of the production cycle from component receipt to factory acceptance test are rigorously controlled. Furthermore, use of proven components and design solutions results in high camera reliability.

The RH-300 (Puffin) high rad underwater camera incorporates an all-magnetic Chalnicon tube to provide excellent resolution, freedom from image burn-in and good sensitivity over a wide spectral range within a small rugged package.

The RH-300 uses carefully selected components and materials ensure that the radiation tolerant underwater camera will survive and provide high quality pictures in environments subjected to high levels of ionizing radiation. Completed tests successfully demonstrated dose rates greater than 1 x 10⁶ Rad/hr and a total dose rate greater than 2 x 10⁸ Rad.

One of the many benefits with the RH-300 radiation tolerant underwater camera is the design functionality of the exterior housing which allows for easy access into the internal cavity and components when performing field maintenance. Printed circuit scanning coils, developed in conjunction with wide-band video processing circuits, ensure the full potential of the Chalnicon tube. The primary design virtually eliminates the need for regular readjustment during the long operating life of the system. Among its uncommon features is a tube beam current stabilizer, which compensates automatically as the tube’s cathode emission diminishes with age.

The RTC-3, Radiation Tolerant Camera, was specifically developed for close-up inspection in high radiation areas, and is one of two interchangeable underwater cameras on the Convertible Viewing System (CVS). Enhanced Chalnicon tube technology incorporated into the design of the RTC-3 allows the camera to provide a higher level of temperature and radiation tolerance than any other camera of its type in the industry.

The RTC-3 features a 3:1, non-browning zoom lens with an additional Analog 2x zoom. An internal LED light ring is built into the face of the underwater camera. For increased versatility, the RTC-3 can be equipped with removable bracketry to mount additional external lighting.

Another exciting feature of the RTC-3 is its simple construction. All of the camera electronics are housed in a single unit allowing for easy set up, operation and maintenance. The camera no longer requires tuning to each controller and is also highly immune to outside noise.

The RH-400 (Petrel) black & white camera incorporates an all-magnetic Chalnicon tube to provide excellent resolution, freedom from image burn-in and good sensitivity over a wide spectral range within a small rugged package.

Carefully selected components and materials ensure that the RH-400 underwater camera will survive and provide high quality pictures in environments subjected to high levels of ionizing radiation. Completed tests successfully demonstrated dose rates greater than 1 x 10⁶ Rad/hr and a total dose rate greater than 7 x 10⁷ Rad.

The IR-400 (Swift) was designed specifically for inspection applications in the nuclear industry where appreciable levels of radiation are present but the cost of a highly radiation tolerant camera such as those in our RH-300 (Puffin) and RH-400 (Petrel) ranges cannot be justified. Its tolerance level fits neatly in between these cameras by utilizing CCD solid-state equipment.

The IR-400 camera has been designed avoiding the use of components known to be vulnerable to radiation, such as CMOS integrated circuits and IC voltage regulators. The design uses only 2 printed circuit boards which are easily replaced or removed for maintenance; the tube is simple to replace and the optical focus position can be set from the rear of the camera to accommodate variations in lenses and also to allow close focus setting.
