Temperature-Controlled and Heat-Sink Lens Tubes

• SM1 Lens Tube Featuring Controlled Heating for Ø1" Optics
• Embedded NTC 10 kΩ Thermistor Provides Temperature Feedback
• Directly Compatible with Our SM1-Threaded (1.035"-40) Lens Tubes

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.

HSLT2 Heat-Sink Lens Tube Secured to a QTH10 Tungsten-Halogen Lamp

• Lens Tubes Equipped with Heat Sink for Passive Cooling
• Offers 0.25 °C/W Thermal Resistance Over 2.10" (53.3 mm) Length
• Internal SM1 (1.035"-40) Threading Directly Compatible with Our Ø1" Lens Tubes
• External SM2 (2.035"-40) Threading for Compatibility with Our Ø2" Lens Tubes

The HSLT2 Passive-Heat-Sink Lens Tube provides the ability to cool down a lens tube setup that may be subject to an unusual amount of heat. By providing a total surface area of 79 square inches (510 cm²), it provides a thermal resistance of 0.25 °C/W. Ø1" optical components can be mounted into the HSLT2 lens tube using two SM1RR retaining rings (included). This lens tube features internal SM1 threading and external SM2 threading for compatibility with our SM1 and SM2 Lens Tubes, respectively. It can also be mounted to SM05, SM30, or SM3 setups using our Lens Tube Adapters.
