As best as I have been able to tell, it arrived in good collimation itself (adjusting its rotation in the focuser did not change the location of the dot on the primary mirror), and the results in my images on an F4 scope reveal it is genuinely creating a well collimated setup, as the tolerance at F4 is rather tight.The only way it would be better, is if the laser were a bit brighter, and if the beam were more consistently sharp when showing up on the acryllic screen when it returns from the secondary mirror. Sometimes it shows up as a nice dot and other times it seems rather smudgy. Still, results speak for themselves and it seems to be a very good product.

Artifex Engineering offers custom rod lenses for various applications such as endoscopes. A wide range of substrates are available in custom sizes, specifications and coatings to suit your requirements. We look forward to your inquiry.

This is the best Budget Laser Collimator I have used. It's not going to break the bank. Most important of all, the collimator fires a single tight round laser dot. I have found it very good when collimating my F5 Newtonians.

Knight Optical offers standard rod lenses manufactured from borosilicate. We can also provide custom rod lenses, for example manufactured from UV fused or with an applied coating.

The Baader Laser Collimator has a precision-etched reticule featuring hundreds of tiny cross-hairs which light up brightly when the reflected laser beam touches them.  Easily visible from any viewing angle.  Even if the optics are off to a large degree, the reflected beam can be traced right through to the reticule and the telescope optics adjusted until the beam falls back on itself.

Anyone, not only suppliers themselves, can report additional suppliers. If possible, please provide a web address showing that this supplier indeed offers such products.

Note 2: For any laser collimator to be effective it needs to be fitted to a well-made focuser. The regular rack-and-pinion style focuser fitted to many beginner/intermediate telescopes lacks precision and rigidity. If in doubt please contact us for advice.

Rod lenses perform in a manner analogous to a standard cylinder lens, and can be used in beam shaping and to focus collimated light into a line. Our rod lenses play a key part in many laser and imaging optical assemblies, and can be used for UV, visible and NIR applications.

The Baader Laser Collimator is a great peice of kit, well engineered, and make's collumating a breeze. It has been designed well so not to loose columation itself! Only slight negative is that the batteries are very small and will sometimes flip when trying too drop them in toget the right polarity.

Having struggled with an ordinary Cheshire I decided to try a laser after seeing videos. Adjusting the secondary was a breeze, but due to the flat screen it took two of us to collimate the main mirror on my 12 inch Newtonian. The red dot on the screen was nice and bright and showed up clearly on the centre of the main mirror for the secondary adjustment. With lasers you can make the small adjustments as the locking nuts are tightened and re -check so easily any time. I didn't time it but it felt that the whole job took only a couple of minutes. Brilliant.

Designed for use in a variety of laser and imaging systems, these components are available in a range of micro sizes for integration into a host of OEM applications. Custom sizes, variations in polishing/ ground surfaces and additional coatings are available upon request.

The Baader Laser Collimator was easy to use , and gives additional confirmation of the collimation provided by the collimation cap . It will be especially useful to tweak the collimation ( if necessary) when the telescope is on the mount at night by small adjustment of the primary mirror screws . I have no issues with this product ..
