Altair Heater for Cooled Cameras with T2 Thread Connection

Altair Heater for Cooled Cameras against Dew Fogging

TEC cooled cameras can get dew on the front optical window if humidity is high, even if they have heated front optical windows. Filter wheels are also affected.

This circular split ring heater fits Altair Hypercam TEC Cooled cameras, as well as most other CCD and CMOS cameras on the market, with a T-Thread on the front. The 2 W heater warms the front housing, reducing fogging in high humidity conditions.

The flexible heating element fits against a flat surface with a hole in the middle for most optics to pass through. Split cable and heater design allows you to install the heater easily without taking your imaging rig apart.

Installation instructions:

You need a mild glue (such as a thin layer of silicon sealant) to attach the heater against the front of your camera. Silicon is easy to remove by just peeling it off, and it won´t damage the camera front like some heaters which use very sticky compounds which and take the anodising off with it.

Use sparingly. An alternative is to just use electrical tape around the edges which also peels off without much residue.

IMPORTANT: You must ensure the two spade contacts cannot touch each other after installation. They must be insulated by wrapping with electrical tape to avoid short-circuits.

NOTE: Dew heaters must ONLY be connected to a reliable, good quality 12 V dew heater controller with a fuse. NEVER connect ANY dew heater to 12 V direct current power source or mains power under any circumstances, no matter what you read on the Internet.
