Filter wheels & Shutters

Filterwheels are an economical way of inserting interference filters in the optical excitation path, but are slower than wavelength switchers. A filterwheel can also be used in the emission path, for example for dual-emission dyes such as SNARF or INDO-1.


 

Sutter Lambda 10-2

The Lambda 10-2 is a microprocessor controlled, high speed filter wheel. Its impressive speed coupled with exceptionally smooth operation make the Lambda 10-2 ideal for research applications involving fluorescence microscopy, ratio imaging, spectrophotometry, visual physiology, or any application requiring rapid and accurate aperture positioning.

  • Uses standard 25 mm diameter interference filters (a 32 mm version is available)
  • May be fitted as excitation filter or emission filter on most microscopes
  • Direct connection adaptors available, or uses optional liquid light guide
  • Switching time between adjacent filters is 55 ms
  • Optional integral shutter
  • Controller operates two wheels
  • Control by keypad, RS-232, or parallel port
  • Compatible with HCImage imaging software

Sutter Lambda 10-C

The Lambda 10-C features the same stepper-motor driven wheel used in the Lambda 10-2 above, but in a more economical package using a different controller, and is ideal for low to medium frame-rate imaging applications requiring only a single wheel.

  • Uses standard 25 mm diameter interference filters
  • All wheel components and shutters are interchangeable with the Lambda 10-2
  • Switching time between adjacent filters is 90 ms with two filters loaded
  • Optional integral shutter
  • Control by keypad, RS-232, or parallel port
  • Compatible with HCImage imaging software

Sutter Smartshutter

The SmartShutter is designed to complement our growing line of optical products and sets a new standard for shutter performance and reliability. In the traditional shutter design there are two or more “leaves” that rub against each other. Given time, the blades will wear down, bind, and the shutter will fail to open. The SmartShutter™ is designed with only one moving part, which virtually eliminates the effects of wear and markedly improves performance. In the traditional shutter design there is an additional issue of the leaves binding in extreme temperature conditions. Our improved design uses heat resistant material that performs well under very high temperature conditions, extending the life of the shutter.

  • 25mm and 35 mm diameter models
  • Open/close times of 8 ms from the command (3 ms from the start of motion)
  • Up to 40 Hz continuously for the 25mm version (20 Hz for the 35mm model)
  • Mountable in Lambda LS and Lambda DG-4/DG-5
