Description

The SM1L10H Temperature-Controlled Lens Tube is a small heating device that is compatible with our Ø1" Lens Tubes. It is an ideal choice for applying heat to mounted optics in order to control their performance as a function of temperature. It can also be used to prevent condensation from forming on optics.

 

Optics can be secured inside the heating chamber with the included SM1RR retaining ring. The SM1L10H contains an embedded NTC 10 kΩ thermistor that provides temperature feedback and allows automated control of the internal heating element. It is directly compatible with our TC200 Temperature Controller.

 

The temperature-controlled lens tube can be post mounted using an SMR1(/M) Fixed Lens Mount.
