WAVES, VIBRATIONS AND SOUND HE-NE LASER FOR INTERFERENCE EXPERIMENTS HE-NE LASER 1 MW Safety filter and shutter. 2885.00 Standard thread for objectives. He-Ne Laser, Modulated, 1 mW Laser like the 2885.00 but with the option of modulating the light beam. The laser is provided with a BNC-connector for connection to a signal generator, CD-player or similar signal source. The light beam intensity will then vary with the applied signal. Well suited for demonstration of optical communication using photodetector no. 4895.50. Maximum modulation frequency: 1 MHz. 2885.20 He-Ne Laser, Modulated, 1 mW The laser emits light with a wavelength of 632.8 nanometers. The emitted light is coherent, i.e. wave fronts propagate in the same phase over a large distance compared with ordinary light sources. The emitted light is highly directional and the beam diameter at the laser is about 0.5 mm increasing very gradually at increasing distances from the laser. The light emitted is not uniformly polarized but changes its polarization at random around the direction of propagation. Light from the laser is well-suited to demonstrations of optical interference. If a line grating is placed in the laser beam, the interference pattern will be clearly visible on a projection screen. The laser can be used for a wide range of applications in geometrical optics, holography, communication etc. 2885.00 He-Ne Laser, 1 mW 2885.10 He-Ne Laser, 2 mW Inteference Pattern Model for Overhead Projector The set consists of two transparent plastic plates with printed wave front patterns for point sources on each plate. If the plates are placed on top of one another and slightly displaced, an interference pattern will appear. The pattern can readily be projected onto a large viewing screen using an overhead projector. 3235.00 Inteference Pattern Set 3235.00 4895.50 Photodetector The photodetector is provided with a photo diode which can convert laser light intensity values to an electrical signal. The signal can be directed to the built in loudspeaker or be used for measurements via the analog and digital output connections. The photodetector can be used for demonstrating communication over a laser beam, fiber optic communication, plotting of interference patterns, etc. The maximum frequency is 1 MHz. 4895.50 Photodetector 29
WAVES, VIBRATIONS AND SOUND Wavelength of Light Apparatus The apparatus is designed to measure the wavelength of light by studying the interference pattern from a double slit. The device contains a built in 12 V auto lamp with a holder for color filters and a millimeter scale with phosphorescent moveable markers. The emitted light is viewed at a distance of about 3 meters through a double slit. The viewer then directs a co-worker to adjust the markers on the millimeter scale so that the distance between them corresponds to 10 interference maxima. Afterwards the distances can be measured and the wavelength of the light can be calculated. The equipment is well-suited to student lab exercises. Red and blue color filters and a double slit are provided.
