CN104520470A - Reduction of radiation thermometry …

Apparatuses for reducing radiation thermometry bias errors in enclosures such as CVD reactors. In one eodiment, a radiation thermometer utilizes an off-focus telecentric lens arrangement. The off-focus telecentric arrangement is focused at infinity, but is utilized to capture radiation from a relatively proximate target (e.g., within a couple meters) that is out of focus.
