Specview is 100% written in Java and is distributed in standalone application, and applet, formats.

The application version requires that either the Java Development Kit (JDK) or Java Runtime Environment (JRE) be installed in your system and accessible from your path. For the applet version, see here.

Specview Version 2.16 was tested under these configurations:

OS Version Java Version
Linux Red Hat 8 1.6.0_10-rc
Mac OS X 10.6.8 1.6.0_33
Windows XP Pro 2002 1.6.0_04

You can check if you have access to the proper JDK or JRE by typing the command

java -version

at a command line window (a.k.a. "DOS prompt" or "Command prompt" window under Windows).

Specview is also distributed as bundled software in the Star View astronomical database browser and analysis tool ( If you have Star View version 7.1 or above already installed, you automatically got Specview as Star View's spectral preview tool.
