Profile rail OCM 650, 300 mm

The high precision optical rails are made out of special anodized aluminum. The rails are the base for various modules attached to carriers.
 

Mounting plate 40 with rotator, spacer block and carrier 20 mm

This element mounts optical plates, like half- and quarter-wave plates, which can rotate around their axis. The rotator has a scale graduation from 0 - 360° at intervals of 5°. The unit is made out of special anodized aluminum and can be directly attached to the optical rail via a carrier 20 mm.
 

Mounting plate OCM 650 for click 30, including carrier 20 mm

Mounting plates are used to hold optical mounts. A characteristic feature of the mounting plates is the “click” mechanism of the inserts based on spring loaded spheres. Snapping in the groove of the inserted click mount, the optical element is kept in an exact position. On the other hand, the system allows a quick and easy change of the mounted inserts.
The mounting plates are made out of special anodized aluminum. Mounted onto the carrier 20 mm, the mounting plates can be placed onto an optical rail.

4 axis adjustment holder KH650, theta, phi, X and Y, including carrier 20 mm

This adjustment holder mounts a Diode Laser or an LED lamp. Using the fine pitch adjustment screws, the optical axis can be aligned within the range of 3 mm. For fine alignment of the angle of the light beam, two additional pitch adjustment screws are attached onto the back of the holder. The holder and the carrier 20 mm are made out of special anodized aluminum and can be placed onto an optical rail.
 

Plano convex lens f=40, mounted in click 30 mount

Different glass lenses are mounted onto a special anodized aluminum click mount 30 mm by two threaded mounting rings to be used in connection with a mounting plate (02.2132).

Quarter wave plate, mounted in click 25 mount

A quarter-wave quartz plate is mounted onto a special anodized aluminum click mount 25 mm by two threaded mounting rings to be used in connection with a mounting plate 40 with rotator (02.2082). The influence of a quarter-wave plate on a light beam can be studied as a function of the rotation angle.

Optical quartz plate, mounted in click 25 mount

An optical quartz plate is mounted onto a special anodized aluminum click mount 25 mm by two threaded mounting rings to be used in connection with a mounting plate 40 with rotator (02.2082). By shining a light beam through the element, the phenomenon of optical activity can be studied as a function of the rotation angle.

Half wave plate, mounted in click 25 mount

A half-wave quartz plate is mounted onto a special anodized aluminum click mount 25 mm by two threaded mounting rings to be used in connection with a mounting plate 40 with rotator (02.2082). The influence of a half-wave plate on a light beam can be studied as a function of the rotation angle.

Acrylic polarisation monitor

The polarization state of a light beam passing through this monitor is determined by the direction of the scattered light. The acrylic block has a size of 50 mm x 40 mm x 15 mm.

LED white in housing
LED red in housing

As universal and easy-to-change light sources, LED lamps are used in optical experiments. The LEDs are mounted onto a 40 mm x 25 mm diameter housing tube made out of special anodized aluminum. For the alignment, the lamps can be fixed onto a four axis adjustment holder mounted onto a carrier. For their operation, the active LDD-05 power supply (07.0206) is required which controls the output power. For the lamps 1 W (white LED: 3W), high brightness LEDs are used.
 

DIMO diode laser module, 532 nm (green)

Due to its collimated beam, this frequency doubled green YAG laser is an ideal light source for experiments dealing with ray tracing and beam propagation. The diode in its 40 mm x 25 mm diameter housing tube made out of special anodized aluminum can be fixed onto a four axis adjustment holder and can be aligned to the optical axis. Driven by the LDD-05 active power supply (07.0206), the output power is controlled in the range from 0 to 3 mW.
 

LDD-05 active power supply

The universal LDD-05 active power supply is used for all laser and LED light sources. It recognizes which source is connected and sets the parameters for it automatically. The unit is equipped with a main switch, a regulation knob for adjusting the laser or LED power and a safety lock. The provided USB bus interface allows control through a personal computer or laptop and qualifies this unit as multimedia source.
The housing is made out of shock-proof plastic with an aluminum front and rear panel.

Voltage: 230 VAC / 50 Hz
Case dimensions: 200 mm x 160 mm x 62 mm.
 

In this unit, the high quality polarizer foil is inserted into a rotatable holder mounted onto a carrier. Using the rotating insert, the polarization direction can be set in degrees (0 - 360°) with a resolution of 2°. The unit is made out of special anodized aluminum. Mounted onto the carrier 20mm, it can be directly attached to the optical rails.

Using this unit, an optical glass plate can be rotated around its axis while the pivot arm is set to the deflected beam. By adjusting the hinge angle, the beam deviation angle can be measured on a scale from -90 - +90° at intervals of 2°. Depending on the arm mounts, intensity and polarization state are determined.
