635 nm Diode Laser Option
 |
|
The 635 nm Diode Laser Module employs solid-state laser technology in a compact, economical package. This low-cost visible diode laser (VDL) module is an alternative to the 632.8 nm air-cooled HeNe laser. |
High Intensity Beam
Cytomation's Visible Diode Laser has a high intensity beam that provides superior performance, as shown in Figure 1.  The six populations differ by 4 orders of magnitude, yet all six of the populations present in the Molecular Probes Linear Flow Deep Red® beads are clearly visible on the graph.
Naturally Elliptical Beam
The 635 nm VDL module produces a naturally elliptical beam. This natural elliptical energy distribution offers greater peak intensity than that provided by the 35 mW HeNe laser using traditional spherical optics. The narrow dimension of the beam is along the direction of the sheath flow. This has two benefits. First, it broadens the laser focus laterally, reducing the variation in cell-to-cell illumination. Second, it overcomes spatial cross-talk at the illumination pinhole strip.
Low Cost Alternative
The 635 nm VDL module provides a low-cost alternative to the 632.8 nm HeNe laser which is often purchased with two and three-laser MoFlo instruments. This lower cost is seen in the cost of purchase and the dollar/milliwatt cost.
Minimal Space Requirements
The 635 nm VDL Module requires no additional space on the MoFlo bench; it mounts to an X-Y-Z positioning stage that is mounted to the Illumination Table. This feature is significant when configuring and upgrading benchtop analyzers (BTA) and benchtop sorters (BTS), which can now hold two lasers on the smallest footprint. A two-laser MoFlo cytometer can also be easily upgraded to three lasers.
