Tropel and ISI were spun out of the GCA/General Signal divestiture. ISI never has had an ownership interest in Tropel. Tropel does still supply lenses to ISI but they are older designs. They supply the 2145 i-line lens and the 3153 duv lens. The 2145 was developed in 1988 and the 3153 was developed in 1990. They also provide the the 2mm 193 exposure lens which was developed about 3 years ago. The last 3153 lens shipped to ISI was about 18 months ago and the system is still at ISI without a buyer.
