Thorlabs Acquires Optical Fiber Processing Company, Vytran

Thorlabs announced today that it has entered into a definitive asset purchase agreement to acquire Vytran from Denmark-based NKT. Headquartered in Morganville, New Jersey, Vytran is a market leader in the production of high performance products to taper and fuse optical fiber. Their fiber processing technologies are utilized in a broad range of precision applications including telecommunications, medical components, fiber lasers, and sensing systems. A closing of the transaction is anticipated to take place in September 2015. “We are excited to have Vytran join the Thorlabs team,” said Alex Cable, President and Founder. “Their expertise and product offering are natural additions to our current fiber draw and cabling competencies. As we bring them on board, we will leverage the extensive experience Thorlabs has in nanopositioning, imaging, electronics, and mechanics to further develop their core competencies so as to remain at the forefront of current market needs while also expanding the product line to address new market opportunities. ” Vytran’s New Jersey manufacturing facility as well as its customer support centers in Exeter, United Kingdom and Hangzhou, China will continue to operate from their current geographical locations. In addition, Thorlabs will fully integrate Vytran’s product line into its ecommerce site and provide service and support through its global offices.

Bright, white light, solid state lamp can now include UV: The NEW SOLA 365 light engines®

Lumencor’s SOLA light engines keep improving and adding new capabilities. Our NEW SOLA SM and SE 365 models make the switch from mercury arc lamps easier than ever.



Bright, white light, solid state lamp can now include UV: The NEW SOLA 365 light engines® Lumencor’s SOLA light engines keep improving and adding new capabilities. Our NEW SOLA SM and SE 365 models make the switch from mercury arc lamps easier than ever. Fluorophores such as DAPI can be efficiently excited using the 365 nm Hg line filter sets you already have. And new applications such as photoactivation of “caged” compounds and ultraviolet-activated polymerization and photosensitization become possible. In all SOLA light engines, an array of visible light sources, operating simultaneously with either a violet or an ultraviolet source, is efficiently combined to generate brilliant white light output. The established SOLA SM and SE II models have violet (~395 nm) sources. The new models contain ultraviolet sources (~365 nm). Why tolerate the limitations of an archaic arc lamp in your microscope when such a reliable and technically superior replacement is within easy reach?

New products from Thorlabs, Liquid Crystal Tunable Filter

Liquid Crystal Tunable Filter

Thorlabs’ Liquid Crystal (LC) Tunable Bandpass Filter incorporates liquid crystal cells sandwiched between polarizing elements, much like Loyt or Solc filters, that are used to quickly change the transmission band within the 420 - 730 nm range (see plot to the bottom right). The KURIOS-WB1 filter tunes continuously over the operating wavelength, providing rapid and vibrationless tuning of the filter's center wavelength. Due to its rapid tuning capabilities, this liquid crystal tunable filter (LCTF) is ideal for applications such as multispectral or hyperspectral imaging (see video below) and is ideal for use with charge-couple devices (CCDs). For instance, using this filter in conjunction with a CCD camera produces images with a much higher accuracy for color representation than using a standard CCD camera with a Bayer mosaic. This technique produces true spectral imaging and can thus show spectral features that would otherwise be impossible to detect.

Recognizing that there is a need for a microscope with a modular structure that can be configured to the experiment, rather than the other way around, we set out to develop the new reference standard in multiphoton microscopy. No longer is the microscope body the central feature around which all other aspects are designed—instead, we have chosen to make the primary scanning path the central feature. Add to that a selection of rigid bodies, numerous auxiliary imaging modalities, detectors, motion control, and laser beam control, and you get our Bergamo II Series in vivo multiphoton microscope. The permutations are endless.

Designed to be integrated with your research, the Bergamo II Series can be readily configured or reconfigured to meet a range of imaging requirements from imaging cells to larger animals. Track multiple-labeled specimens with up to four ultrasensitive GaAsP PMTs. Our extended-field-of-view detector modules maximize the collection of the fluorescence signal from in vivo images, even when the fluorescence is scattered through hundreds of microns of tissue. Capture intracellular dynamics at up to 400 frames per second using our advanced resonant scanner technology. Take full advantage of the ever-evolving spectrum of fluorescent proteins with our proprietary extended-wavelength excitation optics
