Introducing the DS650-25 Driver Kit
| |
|
Welcome to the D&S LASERS web site. The DS650-25 driver provides ultra-stable operation, long-coherence length (14 feet MINIMUM) and locked, high-contrast fringes when used with the specified laser diode (see below) -- specifically fine-tuned for the field of holography. This provides todays holographer with a unit that exceeds the specifications of the "traditional" Helium-Neon gas laser -- and, in addition, at a fraction of the price. The DS650-25 Driver Saves You Money You will also find it much more stable and reliable than the micro-drivers contained in many laser diode modules. If ANY component of a "typical" laser diode module fails (either the micro-driver or the diode itself), the entire epoxied module must be thrown away -- and another ENTIRE unit must be purchased. The DS650-25 driver unit is MODULAR -- ANY of it's terminal-strip mounted electronic components can be easily replaced in minutes. If your diode fails, simply disconnect it from the driver and re-connect another. DO-IT-YOURSELF KIT Features of this system include:
35mW laser diode (specified, see bottom of page) provides 25mW guaranteed optical output power (27-28mW typical). The 658nm-rated laser diode is driven at 2.3 volts (instead of 2.8v) which produces 650nm with this system -- producing brighter reflection holograms than at 658nm. Laser diode must be ordered separately (see below). * High Contrast Fringes Provides bright, high-contrast holograms with sharp edge and shadow detail. Increases diffraction efficiency of all holographic work over HeNe lasers. * D&S "Fringe Lock" Circuit Active optical feedback circuit/IC chip combination completely eliminates fringe drift and jitter that other micro-driver circuits miss. There is NO gas laser on the market that can match the DS650-25's stability out of the box. * Long Coherence Length Completely eliminates beam-path matching in split-beam set-ups -- just set-up your components wherever you place them and shoot. Coherence has been measured out to 14 feet. * Adjustable Focus Optics From a several-micron point to several feet in diameter -- as easy as turning the lens (when used with housing and barrel specified below). * No spatial-filtering needed for single-beam holograms Remove the collimating lens and have a beautifully-clean spread of laser light -- without a spatial-filter -- from 2.5-inch plates to 30 x 40-cm and above. Optical feedback circuit is not effected by removing the lens. * EM/RF Ferrite Girdled Filtering For exceptionally clean power delivered to the diode itself. Filters ambient EM/RF interference. * Quality Electronics The best transistors, capacitors, resistors and IC chip. * AC/DC Operation Run it from batteries or from any standard AC wall transformer that provides clean, regulated 9v DC output. * User-replaceable Fuse Protection Protects both the electronics and diode itself from both spikes and accidental reverse polarity. * Small, Lightweight, Compact Unit Carries easily in pocket, purse or briefcase. Sets up anywhere.

LASER INFORMATION:
For the Laser Diode ($48.78): Click Here 6.4mm Diode Housing and Lens ($21.00): Click Here TIP: I highly recommend using a light coating of silicone heat-sinking compound (found at Radio Shack) to the laser diode when mounting in the housing. Gently tap the diode into place so that the surfaces are in contact.
