Alloy 30 Lens Tube

• Company: ALLVAR
• Type: Lens Tubes
• CTE: -30ppm/°C
• Material: ALLVAR Alloy 30
• Thread: SM1 (1.035"-40)

Alloy SM1 lens tubes are designed for athermal design. The titanium alloy exhibits a negative coefficient of thermal expansion. This means that along its axis it will shrink when heated and expand when cooled.

• Enables CTE tailoring of athermal systems
• Negative CTE (-30 ppm/°C) Lens Tube
• Great for breadboarding ALLVAR Alloy 30 in your design
• Standard SM1 Lens Tube Sizing
• Stackable with standard SM1 Lens tubes (1.035″-40) threaded components
