Restructuring Cost and Reserve [Line Items]
Restructuring plan		In November 2011, the Company announced a strategic initiative (“2011 restructuring”), which aimed to consolidate operations to reduce our cost structure and improve operational efficiency. As part of this initiative, the Company eliminated facilities through consolidation of certain manufacturing, sales and distribution facilities and exit of Semiconductor and Laser Systems businesses. The Company substantially completed the 2011 restructuring program by the end of 2013. During the three and nine months ended September 26, 2014, the Company recorded restructuring costs from facilities exited as part of our 2011 restructuring program. The restructuring costs during the three months ended September 26, 2014 increased as a result of the Company’s tenant exiting the Orlando, Florida facility, which the Company owns. The Company recorded $0.1 million and $0.4 million in depreciation expense for the Orlando, Florida facility during the three and nine months ended September 26, 2014, respectively.
