Objective Heater S

Objective Heater S

The Objec­tive Heater S is designed for the sta­ble heat­ing of micros­cope objectives.


  • Sta­ble heat­ing of micros­cope objec­tives in order to improve the tem­per­a­ture con­di­tions in the obser­va­tion area
  • Slow and homo­ge­neous heat­ing of parts of the objec­tive pre­vents adverse effects on the opti­cal resolution
  • Ver­sions with an oil drain chan­nel have a cir­cu­lar duct around the objec­tive, tak­ing in abun­dant immer­sion oil and lead­ing it through a flex­i­ble tube into a col­lect­ing ves­sel; an O-ring is addi­tion­al­ly insert­ed for a bet­ter sealing
  • A built-in tem­per­a­ture sen­sor reli­ably mon­i­tors the objec­tive temperature
  • For power sup­ply and the con­trol of tem­per­a­ture, the Temp­Mod­ule S is required
  • Avail­able in:
