Lambda 421 Optical Beam Combining System 

The Lambda 421 beam combiner is a new, patented, concept for combining separate light sources with different spectra into a single common output beam. Each separate light source is collimated before entering the optical path through a bandpass filter. The filters for each light source also function as mirrors that reflect the collimated beams from the previous light sources. In the diagram below the optical paths are outlined for each position including the reflections that occur:

Lambda VF-5™ / VF-1™ / VF-10 Tunable Filter Changers

Sutter Instrument has developed several filter changers specially designed for wavelength selection over a wide spectral range to any given nanometer value. The Lambda VF-5™, Lambda VF-10, Lambda VF-1™ employ the innovative VersaChrome® thin-film filter technology from Semrock® to provide outstanding bandpass characteristics such as high transmission (close to 100%), steep edges and out of band blocking. Since these filters pass an image, they are equally suitable for emission and excitation paths.

FEATURES

  • New: Now supported by the Lambda 10-3 with special programming
  • New: Patented white light output capability
  • Wavelength range as wide as 338-900 nm
  • Access any center-wavelength in nanometer increments
  • Images pass through filters making it suitable for both excitation and emission
  • Easily switch between fluorphore combinations
  • Optional liquid light guide offers absolute vibration isolation
  • All the advantages of thin-film technology – high transmission, steep spectral edges, high out-of-band blocking
  • Polarization independence (s and p nearly identical)

APPLICATIONS

  • Hyperspectral imaging wavelength selection
  • Fluorescence microscopy
  • Ratiometric imaging
  • Calcium imaging
  • FURA
  • Optogenetics

Lambda VF-1 Edge™Tunable Filter Changer

To take advantage of the new VersaChrome® Edge filters, Sutter has introduced the Lambda VF-1 Edge system that allows user selection of the both the long and short end of the bandpass in nanometer steps. This new device incorporates two of our VF-1 filter tilting modules and a Sutter Lambda 10-B controller to give direct control over the bandpass via the unit’s keypad or through external control from a computer or other device. Individual VF-1 modules can also be used with the VersaChrome Edge filters to provide tunable high-pass or short pass filtering.

FEATURES

  • Separate tunable high-pass and low-pass filters let user define the bandpass in nanometer steps
  • User selectable band-width and center wavelength
  • Blocking filter ensures best blocking outside bandpass
  • Based on Semrock® VersaChrome Edge technology

APPLICATIONS

  • Hyperspectral imaging wavelength selection
  • Fluorescence microscopy
  • Calcium imaging
  • FURA
  • Optogenetics

Lambda DG-4 Plus / DG-5 Plus High Speed Wavelength Switcher

The Lambda DG-4/DG-5 Plus is a complete illumination system offering speed and versatility for experiments requiring rapid wavelength switching. New digital servo technology allows faster filter switching and 30% greater light output than the first generation DG-4/DG-5. The instrument retains all the advantages of interference filter based systems, yet eliminates the temporal constraints imposed by traditional filter changing devices like filter wheels. Switching between any two wavelengths is achieved in 0.5msec, allowing the user to perform real-time video imaging. The high switching speed of the Lambda DG-4/DG-5 Plus facilitates the ability to follow fast changes in ion concentrations in dual wavelength ratio imaging applications and to monitor other concomitant changes in the studied system at additional wavelengths.

FEATURES

  • NEW: USB support
  • NEW: Built-in SmartShutter® control
  • NEW: Expanded menu options and enhanced triggering
  • Integral shuttering
  • Integral neutral density filtering
  • Two outputs for monitoring filter position
  • Turbo Blanking
  • Direct computer control via parallel, serial, or USB interface
  • Switches in 0.5 msec

COMMON APPLICATIONS

  • Fluorescent microscopy
  • Calcium imaging
  • FURA
  • Optogenetics
  • Ultra high speed wavelength selection
