1. INTRODUCTION 1.1 Introduction The Lambda 721 is an illumination system designed for the rapid change of wavelength derived from up to seven light sources of different wavelengths combined into a single beam. The system comprises of two subsystems: controller with a built-in power supply and an array of seven LED cube and a liquid light guide or fiber couple.
1.2 General Description Figure 1-1. Lambda 721 indicators, controls, and connectors. The Lambda 721 is a new concept for combining up to 7 separate LED cubes with different spectra into a single common output beam. The LED cubes contain the LED, collimating optics, and a filter.
High speed wavelength selection The Lambda 721 is designed to keep the size of the beam combiner small and the optical path short and efficient. Thin-film bandpass filters, such as Semrock’s STR, reflect greater than 90% of out-of-band light. If the band pass of each light source does not overlap, it is possible to use the filters for both attenuation and reflection of the light from the other sources.
The Lambda optical beam combiner is designed for flexibility and expandability. Should your illumination need change over time a simple configuration change and possibly additional filters can produce an entirely different output. Figure 1-3. Lambda 721 LED Spectra Options.

2. INSTALLATION 2.1 Unpacking The Lambda 721 and associated hardware comes packed in a single carton. The following is a list of the components found there. If you believe that any of these components are missing or show obvious signs of damage from shipping, please contact the factory.
5. Refer to the Operations chapter for instructions on turning on the Lambda 721, operating the controls on the front panel, and making connections to the rear panel. LAMBDA 721 OPERATION MANUAL – REV. 1.10C (20210517)
2.3 Configuration The Lambda 721 is shipped with the LED cube configuration set as ordered. The unit can be operated manually and many of its features can be demonstrated without having to make any TTL input, Ring Buffer strobe, or USB connections. After first exploring the manual...

Provides the interface for controlling the Lambda 721 by computer via USB connection. 3.4 Operation The arrangement of the LED cubes in the Lambda 721 allows for up to seven light sources with differing spectral output to be combined and delivered on a common output light path.
PRESS YES OR NO Figure 3-6. Lambda 10 Mode prompt. Pressing YES places the Lambda 721 into Lambda 10 Mode, as shown in the following figure. Pressing NO, causes the next mode prompt (TTL Mode) to display, described next. USING LEDS 1 - 7 PRESS OFF TO END Figure 3-7.
PRESS YES OR NO Figure 3-11. Use Ring Buffer prompt. Pressing YES places the Lambda 721 into Ring Buffer Mode, asking if the current Ring Buffer should be run, as shown in the following figure. Pressing NO, causes the next mode prompt (Setup Mode) to display, described next.
Up to 100 entries are supported in the Ring Buffer. The 100 entry must contain “End RB”. Pressing OFF, exits Ring Buffer Edit mode and enters Setup mode. 3.1 Setup Mode SETUP MODE? PRESS YES OR NO Figure 3-16. Setup Mode prompt screen. LAMBDA 721 OPERATION MANUAL – REV. 1.10C (20210517)
Pressing ENTER starts running the demo. DEMO RUNNING OFF TO STOP Figure 3-20. Demo Mode running screen. Pressing OFF stops the Demo Mode from running, returning the display to the Lambda 10 Mode prompt. LAMBDA 721 OPERATION MANUAL – REV. 1.10C (20210517)
(www.sutter.com). The Lambda 721 requires USB CDM (Combined Driver Model) Version 2.10.00 or higher. The CDM device driver for the Lambda 721 consists of two device drivers: 1) USB device driver, and 2) VCP (Virtual COM Port) device driver. Install the USB device driver first, followed by the VCP device driver.
(e.g., 2 bytes into 16-bit “word” or “short”, or 4 bytes into a 32-bit “long” or “double word”). For the Lambda 721, all Ring Buffer entry values are stored as “unsigned short” (16-bit) values. A 16-bit value is transmitted and received to and from the controller as two contiguous bytes.
Completion indicator NOTE: All Lambda 10 Mode commands for the Lambda 721 correspond to the Lambda 10 series filter wheel movement for Wheel A, Speed 0, Positions 1 – 7. Any other wheel-select, speed settings, and positions 8 – 9 are not supported.
4.3.1 Load Ring Buffer (‘B’ or ‘b’) Command This command begins the ring buffer loading sequence. Once sent, the Lambda 721 waits to receive up to 100 two-byte entry values until the Stop Loading Ring Buffer value is received.

5. MAINTENANCE AND RECONFIGURATION 5.1 Routine Maintenance Routine cleaning of the Lambda 721 system is required to prevent excessive dust accumulations. Wipe all exterior surfaces with a dry, soft, cotton cloth. Periodically inspect all cables ensuring that all connections are made well, and connectors are evenly seated.
