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.

How It Works
A specific wavelength within the wide spectral range of each filter is obtained by adjusting the angle of incidence from 0 to 60 degrees. This tuning causes little or no change in spectral performance of the filter regardless of the state of polarization of the light passing through the filter. The current VersaChrome series has 15 filters covering 338 to 900 nm. By simply selecting the desired center-wavelength on the controller, users can select any combination of filters for the Lambda VF-5 (which holds up to 5 filters), any single filter in the series for the Lambda VF-1 or any one of 10 filters in the VF-10 that uses smaller filters suitable for laser applications.

The controller for these new tunable filter changers is a special version of our Lambda 10-B. Users can select the desired center wavelength in 1nm increments from the keypad, or via the serial or USB ports. This allows control of the Lambda VF instruments with minimal changes to existing software supporting the popular Lambda 10-B controller. A sequence of wavelengths can be stored in the controller and the TTL input can then be used to trigger selection of the wavelengths in the sequence step-to-step. The firmware includes filter-specific data for each of the VersaChrome filters in the series.

The Lambda VF-5
Along with the ability to select any wavelength in the range covered by any combination of 5 VersaChrome filters, the Lambda VF-5 has a patented white-light output mode that allows the user to access the full spectral output of the excitation light source when it is required. White-light output is achieved by capturing the rejected light from the VersaChrome filter at a 45 degree angle and then combining the two beams on the output side of the VF-5. If this configuration is desired, it requires an additional custom light guide and SmartShutter® system.

When using the Lambda VF-5 for emission applications, we suggest installation of the 5 filters with the longer center-wavelengths covering from 430 nm to 800 nm. For excitation applications, we suggest installing the 5 filters with the shortest wavelengths covering 338 to 620 nm. For special applications, any combination of 5 filters could be installed in the Lambda VF-5. The compact Lambda VF-1 accepts any single filter in the series. The single VersaChrome filter installed in the Lambda VF-1 can be changed as needed.

The Lambda VF-1
The Lambda VF-1 accepts any single filter in the series, which can be exchanged with other filters as needed. This model offers faster switching times as well as a more compact and affordable system. When used with the Lambda VF-1, the controller is able to also control a separate filter wheel or SmartShutter.

The Lambda VF-10
The Lambda VF-10 was originally purpose-built for use with white light supercontinuum lasers. The special sized Versachrome filters are 8 mm x 16 mm making them ideally sized for use with a laser beam. The VF-10 also includes an uncoated glass substrate, identical to the Versachrome filter, which is mounted to an additional stepper motor near the output port of the instrument. This uncoated "filter" changes angle simultaneously with the Versachrome filter and compensates for the laser beam displacement that takes place natively when the filter changes angle for wavelength selection.
