The SP400 series are supplied with x10 widefield eyepieces as standard. x15, x20 and measuring eyepieces are available as accessories. The large rectangular mechanical stage has long arm drop down controls and a removable glass plate that allows transmitted illumination and also serves as a support for opaque specimens. The substage condenser (SP400L & SP400BD) is fully focusing and centring with iris diaphragm and filter carrier.

 

The transmitted lighting(SP400L & SP400BD) is 6 volt 30 watt quartz halogen that is rheostat controlled The field iris allows Kohler illumination. For polarised lighting the field lens is capped with a polarisation filter. The incident illumination system incorporates a separate light housing with 6v 30watt quartz halogen source for the SP400 and SP400L and a 6v 50watt system for the bright/dark field (SP400BD) unit. The bulb filament can be accurately positioned using the lamp housing adjusters. The incident light path has an adjustable focus lens, double iris with centring mechanism. There is a rotating plate with filter options.

 

Within the trinocular head is an analyser filter that can be inserted via a push/pull lever into the optical path for both the transmitted and incident illumination. The analyser is fully rotating via a linkage to an external graduated thumb wheel.  The analyser can be removed from the optical path for plain polarised lighting.

 

The trinocular tube will accommodate adapters for CCTV and digital still cameras, including a parallax system for SLR camera backs. A push/pull lever diverts light via a sliding prism to the camera tube. The SP400 is a modern design series of  instruments with an excellent optical performance at a very affordable price.
