Diode Lasers
IFO's RL series of diode lasers is ideal for conducting voice and audio optical transmission experiments as well as common laser and optical experiments. Electrical connections for the analog and digital inputs are the industry-standard, durable banana jacks. In addition, the analog input hs a 3.5mm audio jack for audio nd microphone inputs. This laser is also the only product on the market which features an externally adjustable internal electronic amplifieer with a variable gain from 1 to 50. This feature makes it suitable for low-voltage microphone inputs and higher amplitude signals from AM/FM radios.
Our series lasers offer wider electrical modulation bandwidth capabilities. They are suitable for video laser transmission and conducting standard voice and audio transmission experiments. Analog and digital inputs for these lasers are industry-standard RCA phono jacks.
Applications:
Voice and AM/FM radio transmission
Video transmission (IF-VL only)
Laser leveling experiments
Light shows
Bar code scanning
Particle counting
Refraction and reflection measurements
Polarization experiments

WBS Laser
The WBS Laser is the ulimate educational laser and will be the last laser you'll need to purchase. Why? Because of its versaility which includes dual analog and digital input design, both with very wide electrical modulation capability. The analog input accommodates as low as 100Hz for laser audio communication experiments to as high as 70 Megahertz for simultaneous transmission of color video picture and sound. The digital input accepts all standard +5 logic levels for digital communications experiments. With such fantastic versatility, this one laser can perform all of the following dynamic optical communication demonstrations:
Voice communication
AM/FM radio transmission
Video from camcorder
RF video from VCR
Digital line-of-sight computer links

IF-550: Laser Ray Box with Power Adapter
IF-583: Laser Ray Box and Power Adapter
(packed in impact-resistant, foam-lined container)
The Laser Ray Box produces five parallel and shaply defined light beams ideal for demonstrating optical ray analysis and viewing. Five side-by-side 1mW diode lasers 1.6 cm apart create beams that are 650nm in wavelength for high visibility (readily sseen even in a typical well-lit room). With its commanding visual effects, the Laser Ray Box wille asily and dramatically demonstrate th following light behaviors when used with the appropriate optics:
Light bending due to refraction
Focusing effects of refractive optics
Reflections from mirrors
Fresnel reflections from non-coated lens surfaces
Monochromatic characdter of laser light
Total internal reflection
The bottom of the Lser Ray Box has a magnetized surface for easy adherence to both horizontal and vertical metal surfaces such as steel white or chalk boards for classroom optical demonstrations.
Power to energize the lasing elements is provided by an internal NiCd cell that is charged with the Vac-to-dc power adapter provided.
(This device is rated as a Class II laser product by CDRH regulations because no single beam exceeds 1mW of visible laser radiation or light.)
