Collimated Beam

Collimated light is light whose rays are parallel, and therefore will spread minimally as it propagates. The word is related to "collinear" and implies light that does not disperse with distance (ideally), or that will disperse minimally (in reality). A perfectly collimated beam, with no divergence, cannot be created due to diffraction. Light can be approximately collimated by a number of processes, for instance by means of a collimator. Perfectly collimated light is sometimes said to be focused at infinity. Thus as the distance from a point source increases, the spherical wavefronts become flatter and closer to plane waves, which are perfectly collimated.

Panasonic HL-T1 Laser Collimated Beam Sensors Distributors
HL-T1

The ultra-compact size and yet the high level of performance. Panasonic HL-T1 sensors save space. A high resolution of 4 µm 0.157 mil (at an average 64 cycles) allows high-precision positioning and size judgment. Long sensing range of 500 mm 19.685 in [HL-T1005A(F), HL-T1010A(F)] and 2 m 6.562 ft [HL-T1001A(F)] are available. The sensors are sensitive to minute differences in light intensity, so that they can judge even the opacity of glass. In addition, the amount of light received can be displayed as a percentage to allow you to determine permeation rates. The laser with a beam diameter of Ø1 mm Ø0.039 in can sense extremely small objects with dimensions in micrometers such as bonding wires. The adoption of a Class 1 laser (IEC / JIS) eliminates the need for safety countermeasures, so that these sensors can be used in photoelectric sensor applications with confidence. A wide range of convenient features has been incorporated into the unit's compact body: standard laser beam reception intensity setting / auto scaling setting / measurement processing (various timer and hold functions) / differentiation / monitor focus function. These features make the unit useful for a wide variety of applications.

Panasonic LA Laser Collimated Beam Sensors Distributors
LA

Panasonic LA laser collimated beam sensor conforms to the Class 1 laser stipulated in IEC 60825-1: 2001 and JIS C 6802: 2005. Hence, safety measures such as protective gear are not necessary. Four monitoring LEDs help you to easily align the emitter and the receiver. Panasonic LA-511 conforms to FDA Class I. It is approved for use in U.S.A. by FDA. The side view attachment (optional) enables versatile mounting styles.

Panasonic LA-300 LED Collimated Beam Sensors Distributors
LA-300

Panasonic LA-300 LED collimated beam type which is as accurate as a laser sensor, but much safer. Since a red LED, harmless to the eyes, has been incorporated as the beam source, you are free from strict laser safety regulations. Moreover, due to the red LED beam source, the measuring spot is visible, which makes positioning of the object simple. Its emitter and receiver are much smaller compared to those of the amplifier built-in type (LA-510). Hence, they can be installed even in a narrow space inside an automatic assembly machine, etc. For the analog output, in addition to the span adjustment function, a convenient shift function which enables the analog voltage to be shifted by ±0.5 V has been incorporated. Beam alignment is easy by using the target label (accessory). Further, the 3-stage stability indicators on the amplifier indicate the incident beam level at a glance.

Panasonic LD Edge Detection Sensors Distributors
LD

Safety countermeasures, such as protective gear, etc., are not required since Panasonic LD-600 uses a Class 1 laser as per JIS standards, and LD-601 uses a Class II laser as per FDA standards. Troublesome optical beam alignment is not required since the emitter and the receiver are mounted on one body. FDA standard (Class II) conforming model LD-601 is available. A red semiconductor laser is used as the emitting device and CCD is used as the receiving device. An ideally parallel optical beam is emitted achieving highly accurate measurement. Shading correction function which compensates for receiver sensitivity variation and generates a uniform sensitivity distribution has been incorporated. Stable sensing over extended periods of time is possible. The sensor can be used for various applications with its binary data output with four different sensing modes.
