Vitronic has released the Vinspec Solar VCOFLC1 camera system, which enables exact and reliable front print and colour inspection of solar cells. The new Vinspec Solar VCOFLC1 camera system combines front print and colour inspection, and performs exact and reliable quality inspection and cell classification. The camera is easy to operate and calibrate, and is reliable and robust at competitive pricing. Vitronic provides a standard calibration tool to define the colour classes and borderlines. Even if several cell testers have to be operated and tool matching is required, the set-up process only needs to be carried out once and the classification rules can be copied to all other testers.

The inspection system can be used for both mono and multicrystalline silicon cells. Its throughput achieves more than 2,400 cells per hour and the sorting pureness is higher than 99.8 per cent.

The sensor box consists of a colour line scan camera with four 4,096-pixel lines, a white LED illumination module, a backlight and a computing subsystem.


At the 2013 Control trade fair, Carl Zeiss presented its new Hardware Auto Focus and cleanroom kit for the Axio Imager Vario microscope system. The company says the

Hardware Auto Focus is ideal for surface inspections on reflective, low-contrast samples. In transmitted and reflected light (brightfield, darkfield, polarisation contrast and oblique illumination), the focus system ensures high precision down to 0.3 of the depth of field of the objective lens.

The sensor registers

changes to the focus position and automatically and quickly compensates any deviations via direct access to the Z drive of the microscope. As a result, even large samples such as monitors and solar panels in XY direction remain in focus.

The Hardware Auto Focus

works ideally with Zeiss AxioVision software and is fully integrated in modules such as MosaiX for automated overview image capture. Axio Imager Vario is certified for cleanroom use in accordance


Flir Systems has introduced the Flir Microscopy Stand, a complete solution for thermal evaluation of very small objects. The Flir Microscopy Stand comprises a Flir SC5000 series thermal imaging camera with a 3x or 5x microscopic lens and high-precision xyz stage for accurate positioning. It is capable of accurate temperature measurement on targets as small as 3µm2

. The system is

able to deliver very high spatial resolution for microscopic thermal evaluation of electronic and photovoltaic components. Equipped with a cooled Indium Antimonide (InSb)


focal plane array detector, the SC5000 camera combines high spatial resolution with excellent sensitivity and accuracy. Its 320 x 256 or 640 x 512 pixels format InSb focal plane array delivers a 380Hz or 100Hz frame rate respectively.

The use of Flir’s read-out integrated circuit technology ensures low noise and high pixel rate, without compromising sensitivity. A smart external triggering feature allows synchronisation of image capture to fast events. The camera uses either GigE or CamLink interfaces.

with DIN EN ISO 14644-1 and, with the cleanroom kit, fulfils the requirements of ISO 5, the most commonly used cleanroom class. This corresponds to the original FED STD 209E (1992) standard of class 100.

Extensive accessories, such as the 7x turret with particle protection and sneeze guard, ensure that samples such as wafers and photomasks are clean at all times.
