These special lights generate a dark field over a larger measuring area thanks to their special reflector.
In contrast, the measuring area of commercially available dark field lights is often only very narrow.
The planistar light hood was originally developed specifically for the surface inspection of wafers.
If you cannot find a suitable light in our extensive standard range, we will be happy to offer you LED lighting according to your requirements.
The targeted oblique incidence of light helps to show edges, scratches, embossing, indentations and elevations more clearly. The optical features in the surface appear much brighter compared to plain surfaces and are easier to identify thanks to our dark field illumination.
The special feature of this module is that this lighting has been developed for continuous operation as well as for flash mode. This allows it to be set up in continuous mode and later operated in flash mode. The switching inputs respond to every rising edge from 5 V TTL to 24 V PLC.
No other external controllers are required, everything is built into the light.
Our light hood was originally developed by planistar specifically for inspecting solar wafers. It is characterized by very uniform illumination on the measuring surface. The technology is now used wherever shiny surfaces need to be inspected.
The special feature of this module is that the hood has been developed for continuous operation as well as for flash mode. This allows it to be set up for continuous operation and later operated in flash mode. The switching inputs react from 5 V TTL up to 24 V PLC to every rising edge.
No other external controllers are required, everything is built into the light.
This is precisely where our strength lies. Because planistar manufactures the lights in-house, we can produce customised backlighting with short delivery times.
So you don't have to follow our standard programme. We adapt exactly to your requirements and the conditions on site.
This saves you costs in theOur production processes are planned in such a way that a customised light has almost the same throughput as a standard light. The only difference is that the customised luminaire is precisely documented. This means that we are able to supply replacements even years later.

Lights direct from the manufacturer
When revising the product series, we always take sustainability into account, as many small details add up to a big picture.
This starts with saving resources and energy, the right choice of materials we use, right through to packaging and disposal.
In our lamps, the LED controllers are always built-in to the lamp. This prevents operating errors and accidental damage.
In order to achieve optimum interaction between the LED and the control unit, the electronics are also developed in-house and manufactured exclusively for us by a regional company.
The installation of the controller in the light offers a decisive advantage, especially for applications with flash operation. The very high and short flash current is generated and stored in the luminaire. The currents in the supply line can thus be reduced accordingly. This principle helps to reduce the risk of EMC interference.
The internal microcontroller monitors the pulse-pause ratio and only allows a new pulse after 1:5. This prevents the LEDs from overheating and being damaged by the flash mode.
In flash mode, the pulse duration is limited to a maximum of 1.5 ms. Longer trigger times are referred to as switching mode.
Our devices reach 80% of their brightness 80µs after the input signal has been applied. The brightness is not the same as the voltage at the LED.
The days when LEDs did not generate any heat are long gone. Due to increasingly powerful technology, it is important to design optimum thermal management for the entire fitting.
Because the only death for an LED is heat death. For this reason, the heat at the LEDs determines the service life of the entire luminaire.
Our mostly 2 mm aluminum housings serve as a large cooling surface which, depending on the application, can be supported by additional heat sinks.
