Cold Filter / CLDF-50S
The principle of the cold filter is similar to the glass that is used in a halogen lamp to protect the heat. It enables the visible range to transmit and cut-off the IR range (heat).

◦The feature of the dielectric optical coating filter is to have a steep decline of transmittance from the visible range to IR range. In addition to this; the heat absorption filter is efficient for transmitting at the visible range and cutting off the IR range.
◦It is frequently used as a IR cut filter on a CCD sensor.
◦It is also used as a filter to cut-off the heat from the illumination in a biological microscope to avoid heating up the specimen.

| Attention | ▶The transmittance graph drops on the long side of the visible range when the incident angle is slightly slanting. ▶When placing the filter too close to a light source, the heat absorption may damage the filter due to a rapid change of the temperature. ▶The backside of the cold filter is not coated with AR. The absorption filter may have a backside reflectance value of 4%, a total of 20% of loss can occurred. |
