What does SWK mean in TRANSPORTATION

The SWK design allows for a wider field of view than other lens designs; this means it can capture more of the sky with fewer objects appearing distorted or out of focus. Additionally, it also produces sharper and brighter images of faint objects, allowing for easier observation and tracking of celestial bodies.

Any telescope that uses an eyepiece can be fitted with an SWK lens, including refractor and reflector telescopes. It should be noted that some older refractor telescopic models may need an adaptor to accept an SWK lens as they do not have a universal fitting system.

As with any type of lenses, there are tradeoffs when using an SWK lens; because they are larger than other lenses, they tend to introduce more aberrations due to distortion from chromatic aberration or coma; additionally, having such a large field-of-view at one's disposal may lead to difficulty in accurately focusing on certain targets that require precise focusing adjustments.

Proper maintenance and care procedures should be followed for any type of optic device, but especially for those used in astronomy such as the telescopes fitted with an SWK lens. Before using your telescope each time, inspect it for dust or dirt on the optics; keep your telescope covered when not in use; use only lint-free cloths when cleaning your optic; store you telescope indoors when possible; and allow it time to cool down before beginning your observations each night due to thermal expansion caused by changes in temperature during nighttime hours could affect optical performance if immediate observing begins after dark.
