Subsequent Events [Abstract]
Subsequent Events	Note 21. Subsequent Events The Company paid approximately $22.4 million in tariffs imposed under the IEEPA. Subsequent to June 27, 2026, the Company received approximately $11.0 million comprised primarily of tariff refunds (recovery of cost of sales) and related statutory interest associated with previously submitted IEEPA refund claims. These amounts were not recognized as of June 27, 2026 because the recognition criteria for contingent gains had not been met as of the balance sheet date. On July 9, 2026, the Company completed the acquisition of substantially all of the assets of Direct Optical Research Company, a provider of optical fiber connector end-face quality measurement systems and interferometer technology. The transaction provides for base consideration of $14.0 million, subject to customary purchase price adjustments, and additional contingent consideration of up to $5.0 million based on the achievement of specified post-closing milestones. The acquisition will be included in the NSE segment and is expected to strengthen the Company's optical measurement technology portfolio and expand its capabilities in fiber optic test and measurement solutions. Due to the closing of the acquisition subsequent to the fiscal year-end, the Company is currently determining the fair value of the acquired assets necessary to develop the purchase price allocation. Accordingly, it is not practicable to disclose the preliminary allocation of the purchase price as of the date these financial statements were issued.
