1 LASER POINTER Class ll laser pointers (≤ 1mW), available in 3 wave- lengths: Red (650nm); Green (532nm); Violet (405nm). The violet laser pointer can be used to demonstrate TIR (Total Internal Reflection) in tonic water. Requires 2 x AAA batteries (not supplied). Cat No. Description Colour Wavelength Price Per OLE-110-100 Laser Pointer Red 650nm 18.75 ea. OLE-110-150 Laser Pointer Green 532nm 45.00 ea. OLE-110-200 Laser Pointer Violet 405nm 49.98 ea. 1 LASER POINTER - CONSTANT ON/OFF Class II (≤ 1mW) laser point- ers, each featuring a constantly on/constantly off switch, which allows the laser to be mounted for experimental use without the need to keep holding the switch down. Available in 532nm (green) or 650nm (red) laser pointers. Require 2 x AAA batteries (not supplied). Cat No. Description Colour Wavelength Price Per OLE-130-532 Green laser pointer, constant on/off, 532nm 49.98 ea. OLE-130-650 Red laser pointer, constant on/off, 650nm 37.50 ea. 2 LASER POINTER STAND - ADJUSTABLE -NEW! This Adjustable Laser Stand from Lascells provides a great, hands-free solution, for holding/clamp- ing a laser pointer at a user-defined height and angle. The angle can be adjusted through a full 360-degree range, and the height can be adjusted through a range of 10 cm. This robust acrylic stand has a wide base, provid- ing excellent stability. Laser pointer not included. Cat No. Description Price Per OLE-520-100 Laser Pointer Stand - Adjustable 11.27 ea. LASCELLS LASER SYSTEM The Lascells semiconductor laser contains two independently controlled laser diodes, one at the standard 650nm red and a second at 532nm green. Both lasers may be simultaneously passed through a double slit slide and both diffraction patterns may be displayed one above the other for an immediate comparison. The unit is equipped with internal 1 MHz modulation which when used in conjunction with the laser receiver and an oscilloscope allows the speed of light to be determined in the laboratory. In addition, the facility to modulate the laser from an external source is provided allowing audio to be sent to the receiver from a smartphone or MP3 player. The apparatus is switched on/off using a removable key, to prevent unau- thorised use, and is supplied with a 9V power supply and full instructions. Also available is a dual purpose laser receiver, designed for use with the Lascells Dual Colour laser, the unit contains a planar chip photodiode tied to a 1Mhz amplifier for speed of light calculations along with an audio amplifier for demonstrating data transmission using light. The unit is powered by a 9V DC supply (included) and has a built in speaker for audio reception. The amplified audio is also brought out to 4mm sockets on the front panel for observation or connection to a secondary driver such as the Rubens tube. When using the receiver for speed of light calculations the audio amplifier is disabled, with the signal brought to the front panel only for monitoring using an oscilloscope.
